construction of carbon–sulfur bonds has been achieved via halogen-free Cs2CO3-promoted cross dehydrogenative coupling (CDC) of thiophenols with acetonitrile. This transformation provides a straightforward route to the synthesis of sulfenylated acetonitriles in up to 80% yield.

Substituted phenylthioamidine compounds such as 2-(4-chlorophenylthio)acetamidine; 2-(4-chlorophenylthio)-acetamidoxime; and their pharmaceutically acceptable salts are prepared by the reaction of a substituted phenylthioacetonitrile with hydroxylamine hydrochloride or with methanol followed by ammonium chloride. The compounds have antimicrobial activity and also inhibit ADP-induced aggregation of blood platelets.
Quantum mechanics calculation showed that A29 had a higher highest occupied molecular orbit (HOMO) energy and lower vertical ionization potential (IP) value compared to the high bee toxic imidacloprid, showing potentially low bee toxicity. Bee toxicity predictive model also indicated that A29 was nontoxic to honeybees. Our present work identified an innovative insecticidal scaffold and might facilitate
