摘要:Process for the synthesis of alpha -chlorinated chloroformates, and new alpha -chlorinated chloroformates. The invention relates to a new process for the manufacture of alpha -chlorinated chloroformates and, to new alpha -chlorinated chloroformates as new industrial products. The process according to the invention consists of a synthesis, by catalytic phosgenation, of alpha -chlorinated chloroformates of the formula: in which: R represents a substituted or unsubstituted hydrocarbon radical and m represents an integer superior or equal to one, this synthesis consisting in reacting phosgene with the aldehyde R-CHO)m, in the presence of a catalyst which is an organic or inorganic substance which is capable in a medium containing an aldehyde of the formula R-CHO)m, phosgene and, possibly, a solvent, of generating a pair of ions one of which is an halogenide anion and the other is a cation which is sufficiently separated from said halogenide anion so as to give to the latter a nucleophilic power enabling it to react with the function(s) aldehyde of the molecule R-CHO)m.

摘要:Aryl difluoromethyl sulfone adds to aldehydes under phase transfer conditions to give novel substituted alcohols of the general formula n n RCH(OH)CF.sub.2 SO.sub.2 Ar (I) n n wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.
