The reactions of diphenyldiselenide and dialkyl disulfides with aldehydes in the presence of In–TMSCl have been investigated. Aliphatic aldehydes provide the corresponding selenoacetals and aromatic aldehydes lead predominantly to benzyl phenyl selenides on reaction with diphenyldiselenide. However, the reaction of dimethyl disulfide and diphenyl disulfide with both aromatic and aliphatic aldehydes

the main route of the new reaction of dichloromethylarenes with S-methyl diethylthiophosphinate has been predicted and experimentally confirmed on the basis of the electronic structure of the S-alkyl esters of P(IV) acids. The processes of the mono- and di(dechloromethylthioylation) of dichloromethyl group have been realized. A new approach to the synthesis of the arenecarbaldehyde dimethyl dithioacetals

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
