An Approach to Biologically Important S-Heterocycles, Dithiocarbamyls, and
Relevant Phosphono Derivatives. — The reactions of dithiolthione derivative
28- 046 Their
(I) and tetramethylthiuram disulfide (X) with unsaturated [(II), (XII)] and active (V)
phosphonium salts as well as the phosphonate carbanions (VIII) enables the synthesis
of new S-heterocycles, e.g. (VI) and (VII), dithiocarbamyls, e.g. (XIII), and their
phosphono derivatives (IX) and (XI) by insertion of carbanions between two sulfur atoms. Selective examples are screened against bollworms (cotton). Compounds (IX)
and (XI) display significant activity towards all tested pests. — (KHIDRE, M. D.;
