A 3-methoxy-2-phenyl-acrylic ester of the formula ##STR36## in which R represents optionally substituted alkyl, optionally substituted cycloalkyl or substituted aryl, and
- n is 0 or 1
- with the exception of methyl 2-N-(benzoyl)-thiocarbamoyloxy!-phenyl-3-methoxy-acrylate.
A process for preparing a 3-methoxy-2-phenyl-acrylic ester of the formula ##STR38## in which R represents optionally substituted alkyl, optionally substituted cycloalkyl, or substituted aryl, and
- n is 0 or 1
- with the exception of methyl 2-N-(benzoyl)-thiocarbamoyloxy!-phenyl-3-methoxy-acrylate, which comprises reacting a 2(2-hydroxyphenyl)-3-methoxy-acrylate of the formula ##STR39## with an N-acyl-isothiocyanate of the formula ##STR40## in which R and n have the abovementioned meaning,
