Reaction of borane-dimethyl sulfide complex with aromatic acids: Access to methyl compounds or to benzyl dimethyl sulphonium salts

Article abstract of DOI:10.1016/0040-4039(91)85078-J

In certain conditions, the action of borane dimethyl sulfide (BMS) with aromatic carboxylic acids leads to the corresponding methyl derivatives or, in the presence of BF₃, to the benzyl dimethyl sulphonium salts.
