摘要

Regio-and stereoselective hydrosilylation of terminal alkynes on solid support using diisopropyl hydrosilanes yielding β-(E)-vinyl silanes with excellent selectivity is reported. The hydrosilylation is catalyzed by Pt (DVDS)/P (iBuNCH2CH2) 3N (DVDS= 1, 3-divinyl-1, 1, 3, 3-tetramethyl-disiloxane), in which the bulky proazaphosphatrane ligand plays a key role for the selectivity. The immobilized products are characterized with gel phase13C NMR ...
