Phema 2-bromoisobutyryl bromide

WebDescription 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. WebThe pure PHEMA displays two broad-featured peaks at 2θ = 18.3°, 29.2° that are characteristic of an amorphous polymer. As portrayed in Scheme 1, BrPEPBr is apt to form a stable, single PEO-bent conformation in order to self-assemble with γ …
