REACTION OF ARACYL- AND ALKOXYCARBONYLMETHYLSELENONIUM SALTS WITH NUCLEOPHILIC REAGENTS
A method is proposed for the synthesis of α-methylselenium derivatives of aryl and heteryl methyl ketones and ethyl acetate by demethylation of readily available aracyl-, heteroacyl-, and methoxycarbonylmethylselenonium salts with triethylamine.It was established that triphenylphosphine cleaves dimethylphenacylselenonium bromide both at the Se-methyl and at the Se-CH2COPh bond (preferentially).Triphenylphosphine selenide is formed in this reaction in addition to the corresponding phosphonium salts.
