摘要：

The synthesis of E-alkenylstannanes from aldehydes and a mixture of Bu(3)SnCHBr(2), LiI and CrCl2 is described. A mechanism is proposed to account for the alkene geometry in chromium(II)-mediated alkene synthesis which involves stereoselective addition by a gem-dichromium reagent to an aldehyde followed by a stereospecific elimination step.
