 It was named after the Russian chemist Vasilii Semenovich Abramov (1904–1968) in 1957.Electron-rich sources of phosphorus such as phosphites, phosphonites, and phosphinites may undergo nucleophilic addition to carbon atoms in simple carbonyl compounds.When fully esterified phosphites are used (Abramov reaction), neutralization of the resulting tetrahedral intermediate usually occurs via the transfer of an alkyl or silyl group from an oxygen attached to phosphorus to the newly created alkoxide center.
