TL;DR: In this article, a useful method for the preparations of 1-alkenes from terminal allylic carbonates and acetates by the palladium-catalyzed reaction with formates is described.
Abstract: A useful method for the preparations of 1-alkenes from terminal allylic carbonates and acetates by the palladium-catalyzed reaction with formates is described. Formic acid-triethylamine is a suitable reductant. As catalyst, Pd2(dba)3CHCl3-P(n-Bu)3, gave the best results. 0.05 0.2mol% being sufficient (turnover 500 2000). Using this method, various 1-alkenes were prepared in good yields with high selectivity.
TL;DR: In this paper, the methodes de clivage reducteur de groupes nitro aliphatiques utilisant le tributylstannane and leurs applications in synthese organique are discussed.
