    摘要: A process for the production of low molecular weight polymers by free radical polymerisation of one or more monomers in the presence of a chain transfer agent, characterized in that the chain transfer agent comprises one or more compounds of general formula (I), wherein R is a hydrogen atom, an alkyl group, or a group capable of activating the vinylic carbon towards free radical addition; R represents an optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, or optionally substituted satured, unsatured or aromatic carbocyclic or heterocyclic ring; and Z represents an oxygen, sulphur, phosphorus, or nitrogen atom bound to another atom or group of atoms in order to satisfy its valency.

    摘要: The present invention provides a process comprising reacting a halogenated thiocarbonyl compound represented by Formula (1): wherein Ar is an optionally substituted aryl group and X is a halogen atom, with an Grignard compound represented by Formula (2): R-MgY wherein R is an optionally substituted aryl group or an optionally substituted cycloalkyl group and Y is a halogen atom. This process can produce the desired arylthionocarboxylic acid ester represented by Formula (3): wherein Ar and R are as defined above, in a high yield under relatively mild reaction conditions.
