• Dimethyl 2,6-dibromoheptanedioate acts as a bifunctional initiator in various polymerization reactions. its electrochemical cyclization affords high yields of three- to six-membered dimethyl 1,2-cycloalkanedicarboxylates.dimethyl 2,6-dibromoheptanedioate may be used in the following studies:
• Preparation of difunctional poly(n-butyl acrylate) (pba) macroinitiator
• As initiator for the synthesis of dibromo-terminated polystyrene, via atom transfer radical polymerization (atrp)
• Preparation of polytrithiocarbonate, which serves as reversible addition-fragmentation chain transfer (raft) agent for radical polymerization reactions
