Description

General description

Diethyl meso-2,5-dibromoadipate reacts with N-methylallylamine in the presence of potassium carbonate to yield two diastereomers of diethyl 2-allyl-N-methylpyrrolidine-2,5-dicarboxylate.

Application

Diethyl meso-2,5-dibromoadipate may be employed as difunctional initiator during n-butyl acrylate (n-BuA) polymerization, leading to α,ω-bromo-poly(n-BuA) having narrow molecular weight distribution. It was also used:

• as bifunctional atom transfer radical polymerization (ATRP) initiator
• as initiator during the solution polymerization of octadecyl ester ether dimer by ATRP
• in the synthesis of diethyl 2,5-diazidoadipate
