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.

Application

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.
