The chemistry of β-metallo ketones (or β-metal substituted ketones) has been reviewed. Though attractive and promissing, their chemistry is almost undeveloped compared with rich chemistry of their α-counter part, i. e., α-metal substituted ketones or metal enolates. This may be due to lack in general method for generation of β-metal substituted ketones. The recent approach consisting of desilylative ring cleavage of siloxycyclopropanes with metal salts has been proven successful and has opened new entry to a variety of β-metal substituted ketones. Nonconventional methods for the bond formation at β to carbonyls have been developed with the aid of β-metal substituted ketones.
