Photochemical transformation of telomers i. Photolysis of methyl 2-bromo-4,4,4-trichloro-2-methylbutyrate

ABSTRACT The photochemical reaction of methyl 2-bromo-4,4,4-trichloro-2-methylbutyrate (1) was studied aiming at its chemical modification. The effects of irradiation time, temperature, and


solvent polarity on the photolysis of 1 were investigated. The formation of ten photoproducts was confirmed, and the route of photolysis is proposed. Homolytic cleavage of the carbon-bromine


bond occurred predominantly to induce different types of photoprocesses, such as disproportionation, elimination, hydrogen abstraction, recombination, and addition. The elimination reaction


proceeded contrary to Saytzeff’s law, and the debromine-coupling and addition reactions gave some novel dimeric telomers. SIMILAR CONTENT BEING VIEWED BY OTHERS AUTOPOLYMERIZATION OF
