Atom transfer radical polymerization (ATRP) has been a promising technique to provide polymers with well-defined composition, architecture, and functionality. In most of the ATRP processes, alkyl halides are used as an initiator. 2-Bromo-2-methyl-propionic acid 4-hydroxy-but-2-ynyl ester (BPE) and 2-Bromo-2-methyl-propionic acid but-2-ynyl diester (BPDE) were synthesized by one step reaction which involved on esterification of 2-Bromo-2-methylpropionyl bromide with 2-Butyn-1,4-diol and sufficient purity. 1H NMR has confirmed the structure of the both initiators. This initiator will be very useful in the polymerisation of monomers in order to produce polymers with controlled molecular weight and narrow polydispersity.
