Regioselective alkylation of 1-silyl-2-methylallyl carbanions

Article abstract of DOI:10.1016/0040-4039(91)80637-L

Regioselective alkylations of 1-silyl-2-methylallyl carbanions were achieved by changing the substituents on silicon. γ-Alkylation was favoured by dialkylamino group on silicon, whereas α-alkylation was favoured by an alkoxy substituent on silicon.
