摘要：
Palladium-catalyzed hydrostannylation reactions of alpha-hetero-alkynes and alkynyl esters were achieved with high regio and stereoselectively in the ionic liquid 1-butyl-3-methyl-imidazolium hexafluorophosphate ([bmim][PF6]) at 60 degrees C in high yields. Our system not only avoids the use of highly toxic benzene or volatile THF as solvent but also solves the basic problem of palladium catalyst reuse. ((c) Wiley-VCH Verlag GmbH & Co.
