Synthesis of Chain Transfer Agents for RAFT Polymerization by using DBU

Trithiocarbonate TTC, Dithioester DT containing RAFT chain transfer acid agents are efficiently and conveniently esterified by DBU. The significance of the reaction is mild reaction condition, high yield, easy simple workup, and reduction of reaction time. This protocol providing a useful alternative method for ester synthesis and makes the process very viable or more economic.
