Abstract

Compounds of the general formula <FORM:1120600/C2/1> are disclose wherein X is S or Se or C(R)2; Y is CRv; R is H; R1 is methyl, ethyl or propenyl; RII and RIII are methyl, benzyl or together form a piperidinyl or pyrrolidinyl ring; RIV and RV may be phenyl or may together form a benzene, chlorobenzene or naphthalene ring. A compound in which RII and RIII are methyl is formed by heating 2-(methylene-o -dithiocarboxylic acid methyl ester)-3-methylbenzothiazoline with dimethyl amine; and a compound in which RII and RIII are together piperidinyl is formed by heating the said benzothiazoline with pyrrolidine. The other compounds are prepared analogously.
