2-Bromo-2-methylpropionyl bromide Usage And Synthesis

Chemical Properties

colourless liquid

Usage

α-Bromoisobutyryl bromide has been used: as atom transfer radical polymerization (ATRP) initiator for functionalization of hydroxyl groups present on the surface of graphene oxide 1 to form an N -protected halodienamide which provided four- and five-membered lactams in the presence of copper (I) and a tertiary amine 2 in preparation of polycaprolactone macroinitiator via reaction with oligomeric caprolactone diol 3 and mesoporous silica nanoparticles with ATRP initiator anchored on the exterior surface 4
