Abstract

Allylation of aldehydes with allyltrialkylsilanes is one of the most powerful CC bond forming reactions in organic synthesis. Generally, strong Lewis acids 1., , , and such as TiCl 4 , BF 3 –OEt 2 , NbCl 5 and SnCl 4 were known to catalyse these reactions. Recently, several metal triflates 2., , , , , and such as Sc(OTf) 3 , Yb(OTf) 3 , Zr(OTf) 4 and Hf(OTf) 4 were found to be effective for this transformation. But in most of the cases either a long reaction time or drastic ...
