Synthesis of phosphinodiselenoic acid esters and their application as RAFT agents in styrene polymerization
摘要:
Phosphinodiselenoic acid esters are synthesized from the reaction of chlorodiphenylphosphine and aryl-or alkyl-magnesium bromide in the presence of selenium powder. They are employed as RAFT agents in thermally initiated, styrene polymerization. The phosphinodiselenoic acid esters 6a and 6b showed some degree of control over the radical polymerization of styrene. (C) 2008 Elsevier Ltd. All rights reserved.
