Palladium(0)-catalysed addition of Bun3SnGeMe3 to α,β-acetylenic esters (1a–f) affords predominantly the (E)-2-tri-n-butylstannyl-3-trimethylgermylalk-2-enoates (2a–f), which serve as effective precursors of synthetically useful, stereochemically defined, tetrasubstituted alkenes.
钯(0)催化将Bu n 3 SnGeMe 3加到α,β-炔属酸酯(1a – f)中,主要得到(E)-2-三-正丁基锡烷基-3-三甲基锗烷基-2-烯酸酯(2a – f),其用作合成上有用的,立体化学定义的四取代的烯烃的有效前体。
