- N- (arylsulfonyl) carbamic acid derivatives which can be prepared by process A correspond to the general formula
- Ar represents phenyl, benzyl, naphthyl, pyridyl or thienyl

- the amide derivatives are characterized by vari discard biological effects; While the N- (arylsulfonyl-N'-triazinyl (or -pyrimidinyl)) compounds are primarily known as herbicides, the derivatives containing a phenyl group or an aliphatic or alicyclic group instead of an aromatic N-heterocycle have an antidiabetic, cardiac rhythm-regulating or cancer-inhibiting effect
- the O-esters and S-esters show an antidotum activity against the phytotoxicity of herbicides based on triazine and thiocarbamate or have a herbicidal action themselves.

- S-sulfonylthiocarbamic acid esters are produced in good yield in the alkaline hydrolysis of N- (arylsulfonyl) imino-dithiocarbonic acid dimethyl esters or in the oxidation of N- (arylsulfonyl) -dithiocarbamic acid methyl ester (12 Nippon Kagaku 91) with H 2 O 2 ) 1168-73, CA 75, 19878].
- sulfonylureas, carbamates and thiocarbamates are produced by catalytic carbonylation of N-halosulfonamidates. While this method overcomes many of the disadvantages of the previous methods, its applicability is limited because the aryl group must not contain any groups sensitive to oxidation, acidic or alkaline hydrolysis.
- the invention is based on the knowledge that the arylsulfonylimines of the general formula (II)
- ArSO 2 NCO (III) can be carbonylated if a catalyst is used as a transition metal from the 4th, 5th or 6th period of the periodic table, the oxide, salt, carbonyl or the complex of such a metal in which the coordinative bond by a carbon, tin, nitrogen, phosphorus, arsenic, antimony, oxygen, sulfur, selenium, tellurium and / or halogen atom is formed, and the arylsulfonyl isocyanates of the general formula (III) with compounds of the general formula (IV)

- R 1 , R 2 and R 3 for the forms of the groups listed coupled to a polymer matrix stand with the restriction that at least one of the groups R 1 , R 2 and R 3 represents a hydrocarbon group which is mixed with iodine, sulfur, selenium, Tellurium, phosphorus, arsenic or antimony can form a covalent bond, and
- the catalyst used being a transition metal from the 4th, 5th or 6th period of the periodic system, the oxide, salt, carbonyl or the complex of such a metal, in which the coordinative bond by a carbon, tin or , Nitrogen, phosphorus, arsenic, antimony, oxygen, sulfur, selenium, tellurium and / or halogen atom is formed, where the catalyst can be prepared beforehand or generated in the reaction mixture and as a homogeneous, heterogeneous or heterogenized homogeneous Catalyst is present and is used in a quantity of 10 -3 - 10 mass% based on the starting imine of the general formula II, and the carbonylation reaction at -20 ° C to 200 ° C, preferably -20 ° C to 120 ° C, and a CO partial pressure of 10 5 - 10 7 Pa in a solvent for 0.1-10 hours, and after completion of the carbonylation, the arylsulfonyl isocyanate

Mixtures of these catalysts can also be used.
- the catalyst can be homogeneous, heterogeneous or heterogenized (immobilized). It can have been prepared beforehand, or it can be generated in situ. For example, aluminum oxide, silica gel, activated carbon and organic polymers can be used as carriers for heterogeneous and immobilized catalysts.
- the catalyst is used in an amount of 10 -3-10 mass% based on the starting sulfonylimine.
- the carbon monoxide used for the carbonylation reaction can be used as a pure gas or as a gas mixture. All gases and vapors which are inert to the catalyst and the reactants are suitable as dilution components. Examples include: nitrogen, oxygen, noble gases, air, carbon dioxide, hydrogen, water vapor, vapors from organic solvents. However, some catalysts or reactants can be sensitive to the diluent gas, which is why the diluent gases permitted for the individual catalysts and reaction components can differ.
- the CO partial pressure in the reactor is between 10 5 and 10 7 Pa.
- the carbonylation reaction is carried out at temperatures between -20 ° C and 200 ° C, preferably between 20 ° C and 120 ° C, in particular at temperatures between 20 ° C and 100 ° C.
- the temperature is chosen depending on the activity of the catalyst and the thermal stability of the reactants.
- the carbonylation is either carried out in the presence of the compound IV, or after the carbonylation has ended, the compound IV is added, the target product I being formed.
- the two isocyanates can be easily separated from one another by distillation; the yield is over 80%.
- R phenyl, p-tolyl, piperidyl
- sulfonamides can be reacted with thionyl chloride and chlorocarbonylsulfonyl chloride in the presence of pyridine to give sulfonyl isocyanates [US 4,835,053 / CA 10278564]:
- Sulfonyl isocyanates can be prepared from N-sulfonyldithiocarbamates in a multi-stage synthesis [Nippon Kagaku Zasshi 1970. 91, 1168-73 / CA 75 19878 /]:
- the final step is either heating in xylene or chlorination.
- the chlorosulfonyl isocyanate proved to be suitable in two ways for the preparation of sulfonyl isocyanates [DE 3 132 944 / CA 98.215319 /; Ger. 1 289 526 / CA 70 87312 /]:

- Ph 2 Se (OMe) 2 + ArSO 2 NH 2 - - - - - - - - - - - - - - -> Ph 2 Se NSO 2 Ar (23)
- N-halosulfonamidates can only be formed from relatively few sulfonamides, ie the number of sulfonylimines which can be prepared from them is necessarily limited.
- aggressive (strongly alkaline or strongly acidic) media for example acetic anhydride, are used, or they only run at high temperatures (see, for example, equations (22), (24), (25)), and these circumstances also limit the range of sulfonylimines that can be prepared.
- Many of the methods listed are very time consuming and their yield is low.
- the invention therefore also relates to a process (process C) for preparing the compounds of the general formula (Ha) which form a narrower group of the compounds of the general formula (II)

- a solvent is preferably used as the precipitation solvent inert solvent that does not contain alcoholic hydroxyl groups.
- the organic iodine compound R 1 'I (OAlk) 2 is coupled to a polymer matrix or another solid support.
- This carrier-bound iodine compound can then form the filling of a reactor through which the solvent flows with the other components of the reaction.
- the water can be removed here outside the reactor. It is also advantageous with this solution that the organic iodine compound can be easily recovered after the arylsulfonylamine of the general formula (Ila) has been reacted further (carbonylated).
- reaction to the arylsulfonylimide takes place at room temperature, which means less energy consumption.
- the carbonylation can be carried out at low to medium pressure and temperatures between 20 ° C and 100 ° C, in a homogeneous phase, which enables simple and energy-saving technology.

- the compounds of the general formula (I) listed in Table 1 are prepared by carbonylating sulfonylimines of the general formula (II) and reacting the sulfonyl isocyanates formed as intermediates with compounds of the general formula (IV).
- the qualitative identification of the sulfonyl isocyanates is carried out by IR analysis of the diluted reaction mixture (presence of the bands as NCO, as SO 2 , s SO 2 and optionally as NO 2 , s NO 2 and CO).
