Method for the preparation of thiol(meth)acrylates.

摘要

The invention relates to a method for the preparation of thio(meth)acrylates of the general formula I in which R represents hydrogen or methyl and R1 represents an optionally substituted phenyl radical or an optionally substituted alkyl radical which has 1 to 24 carbon atoms and which may be cyclic, in which (meth)acrylic anhydride of the formula II in which R represents hydrogen or methyl is reacted with an at least stoichiometric amount of a thiol or thiolate of the formula III R1-S-M (III> in which M represents hydrogen or a metal cation and R1 has the meanings given above.
