Visible-Light-Induced Photocatalytic Synthesis of β-Keto Dithiocarbamates via Difunctionalization of Styrenes
A facile photocatalyzed strategy for difunctionalization of styrenes in the presence of CS2 and amines providing β-keto dithiocarbamates has been developed. In the case of 4-nitrostyrene and 2-vinylpyridine, however, only 2-arylethylthiocarbamates are interestingly formed without the aid of photoredox catalysis/TBHP.

A NEW METHOD FOR THE EVALUATION OF THE RELATIVE STABILITY OF ORGANOSULFUR RADICALS BY COMPETITIVE ELIMINATION TECHNIQUE
The relative stability of various organosulfur radicals is estimated by competitive elimination technique using tributyltin radical and acetophenone derivatives having two different sulfur substituents at α and α positions.

Preventive and curative compositions against mycoplasmosis
Use of dithiocarbamic acid derivatives having the structure STR1 in which R1, R2 and R3 are various organic radicals as preventive and curative agents against mycoplasmosis. These derivatives are prepared from the starting materials having the structure STR2 by reaction with carbon disulfide or from the starting materials having the structure STR3 BY REACTION WITH R3 -halide.
