Cadmium mediated allylation of a variety of carbonylcompounds and imines in a Cd/Bu4NBr/THF system afforded excellent yields of the corresponding homoallylic alcohols and amines under very mild reaction conditions.
在Cd / Bu 4 NBr / THF系统中,镉介导的各种羰基化合物和亚胺的烯丙基化在非常温和的反应条件下提供了极佳的相应均烯丙基醇和胺收率。
Allylation of Imines with in situ Generated Allyl Lead Reagents in a PbBr<sub>2</sub>/Al/BF<sub>3</sub>·OEt<sub>2</sub>/Et<sub>2</sub>O System
Reductive addition of allyl bromide to imines has been performed with a combination of a catalytic amount of PbBr2 (0.03–0.1 equiv.) and Al (1 equiv.) in Et2O containing BF3·OEt2 (1.1 equiv).

There is described a process of transferring &agr;,&bgr;-unsaturated alkyl groups to an electrophile (aldehyde, ketone, nitrile, imine, alkyne) by means of a masked zinc alkyl in an aprotic solvent.
