Abstract:
Acyl radical triggered difunctionalizations of aryl olefins have been realized using oxime ester as the acyl precursor for the first time. Irradiation of fac-Ir(ppy)3 and oxime ester by visible light caused scission into three components, which recombined with olefins to yield significant β-carbonyl imides showing good functional group tolerance and high atom economy. Control experiments as well as spectroscopic and electrochemical studies revealed the efficient intermolecular reorganization of oxime ester into styrene with the aid of solvent exchange.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
