IONIC ALKYLATION OF TERTIARY ALKYL HALIDES WITH TETRAALKYLSILANES

Bolestova, G. I.,Parnes, Z. N.

, p. 32 - 36 (2007/10/02)

In the reaction of tertiary alkyl halides with tetraethyl-, tetrapropyl-, tetrabutyl-, and tetraamylsilane in the presence of AlX3 the halogen atom is substituted by the alkyl group with the formation of the corresponding saturated hydrocarbons containing a quaternary carbon atom.As a result of the hydride mobility of the β-hydrogen atom in the tetraalkylsilane ionic hydrogenolysis of the substrate occurs in addition to alkylation, and the degree of hydrogenolysis depends on the alkyl substituent in the silane.
