Abstract: The invention provides electrophilic monohalomethylating reagents, methods for their preparation and methods for preparation of monohalomethylated biologically active compounds using such reagents. Typical monohalomethyl groups transferred are FH2C—, CIH2C— and others. The reagents used for transferal of the groups are described by Formulae A-D: wherein: X?F, CI, Br, I, sulfonate esters, phosphate esters or another leaving group; R11=tetrafluoroborates, inflates, halogen, perchlorate, sulfates, phosphates or carbonates The other variables are as defined in the claims.
Abstract: The invention relates to a process for the preparation of onium salts having a low chloride content by reaction of an onium chloride with an acid, where the hydrochloric acid forming is removed by azeotropic distillation by coordination to an organic solvent which forms an azeotropic mixture with water.
