o-Bis(allyldimethylsilyl)benzene as a remarkably effective allylation agent for carbonyl compounds with Bu4NF catalyst

Add time:08/25/2019    Source:sciencedirect.com

A new type of fluoride ion catalyzed allylation agent, o-bis(allyldimethylsilyl)benzene (1a) and bis(allyldimethylsilyl)methane (1b), can be successfully utilized for various carbonyl substrates. The rate acceleration is ascribable to the shift of equilibrium to complex with Bu4NF by the favorable chelation of bis(silane) toward the fluoride ion.
