Reaction of Dichlorotriphenylphosphorane with Bis(trimethylsilyl) Peroxide. A New Method for the Formation of Electrophilic Chlorine Source

Reactions of dichlorotriphenylphosphorane with bis(trimethylsilyl) peroxide in the presence of some organic compounds have been found to give chlorinated products. Aromatic hydrocarbons bearing electron-donating substituents give the corresponding monochloroarenes, while an enol silyl ether is converted into a-chloro ketone. The mechanism is briefly discussed.
