Synthesis of 2-Aryl-1,1-Bis(Silyl)Alkenes Containing Alkyl(Aryl)Amine Groups

Abstract

4-Alkyl-(aryl)aminobenzaldehydes have been generated via the nucleophilic aromatic substitution reaction of 4-fluorobenzaldehyde with appropriated amines and N-heterocycles using hexadecyltrimethylammonium bromide as catalyst and converted to 1,1-bis(silyl)-1-alkene derivatives via the Peterson olefination reaction. The reaction of (HMe 2 Si) 3 CLi with these aromatic aldehydes led to new 2-aryl-1,1-bis(silyl)alkenes.
