摘要

Abstract Solvated rhodium atoms, prepared by the metal vapour synthesis technique, promote the silylformylation reaction of variously substituted alkynes R 1 R 2 CH (CH 2) n C≡ CH, with catalytic activities comparable with and even higher than more common species such as Rh 4 (CO) 12. Z-Silylalkenals are exclusively formed in high yields (60− 95%) indicating syn addition both of CO and of the silane (Me 2 PhSiH) to the triple bond. ...
