화학적 성질
colourless liquid용도
2-Bromoisobutyryl bromide is used to prepare N-protected halodienamide, which provides four- and five-membered lactams in the presence of copper(I) and a tertiary amine. Further, it is used as atom transfer radical polymerization(ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide. It is also used in preparation of polycaprolactone macroinitiators through reaction with oligomeric caprolactone diol and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface.Synthesis
Bromine was added dropwise to a mixture of isobutyric acid and red phosphorus, and the reaction was carried out at 100°C for 6 hours. Unreacted bromine and hydrogen bromide were distilled off under reduced pressure. After cooling, phosphorous acid was separated to obtain crude 2-Bromoisobutyryl Bromide. The crude product was then fractionated under reduced pressure, and the fraction collected at 91-98°C (13.3 kPa) was the final product.2-브롬-2-메틸프로피오닐브로마이드 준비 용품 및 원자재
