Abstract
The invention comprises new aryloxazolyl-ethylene derivatives of formula <FORM:0835896/IV (b)/1> in which R1 and R2 each represent an alkyl residue. They may be produced by heating two molecular proportions of an ortho-hydroxy-aminoaryl compound with one molecular proportion of thiomalic acid or an alkyl mono- or di-ester thereof. The reaction is advantageously carried out in the temperature range 100-200 DEG C. in an inert organic solvent such as monochlorbenzene, dichlorbenzenes, trichlorbenzenes, nitrobenzenes, toluene, xylenes or cumene. The compounds formed may be treated with agents capable of splitting off water to give di(aryloxazolyl)-ethylenes in accordance with the process described and claimed in Specification 835,897. In the examples details are given of the preparation of <FORM:0835896/IV (b)/2> <FORM:0835896/IV (b)/3> and <FORM:0835896/IV (b)/4> These compounds when heated with zinc chloride lose water to give the corresponding a ,b -di-[benzoxazolyl-(2)]-ethylenes.
