Lanthanum Trichloride: A Simple and Efficient Catalyst for Allylation of Aldehydes with Allyltributylstannane

Abstract

Aldehydes undergo smooth nucleophilic addition with allyltributyl-stannane in the presence of lanthanum trichloride to afford the corresponding homoallylic alcohols in excellent yields. All the reaction conditions were carried out in acetonitrile solvent at room temperature. In all the cases, the catalyst was used in a catalytic amount (10% mol).

Keywords:

• Aldehydes
• allytributylstannane
• homoallylic alcohols
• lanthanum trichloride

Notes

^a All the products were characterized by spectroscopy data.

^b Yields were isolated and not optimized.
