Palladium-catalyzed highly regio-, stereo- and chemoselective carbogermanylation of allenes: a novel method for the synthesis of 2-arylallylgermane derivativesElectronic supplementary information (ESI) available: synthesis and characterization of compounds 4 and 6.

Palladium complexes effectively catalyze the three-component assembly of allenes, aryl iodides and stannylgermane in a highly regio-, stereo- and chemoselective fashion to yield (Z)-allylgermanes in good to excellent yields.

Palladium(0)-catalysed addition of Bun3SnGeMe3 to α,β-acetylenicesters (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。
