Chemistry of Silylketene: A One-Pot Synthesis of α-Silyl Ketones

Abstract
Addition of organocerium reagents 4 prepared from cerium(III) chloride and an alkyl- or aryllithium, to silylketenes 3a-c and the subsequent quenching with aqueous ammonium chloride or alkyl halides 5 gives the corresponding α-silyl ketones 1 in 53-99% yield.
