Abstract

The main route of a new reaction of (dichloromethyl)arenes with S-methyl diethylthiophosphinate is the attack of the thiol sulfur atom (P–SMe) on the methylene carbon atom. A new method for synthesizing dimethyl dithioacetals of arenecarbaldehydes without using highly toxic methanethiol was developed. The suggested approach involves di(dechloromethylthioylation) of the dichloromethyl group of (dichloromethyl)arenes with S-methyl diethylthiophosphinate at a reagent ratio of 1: 2.
