N2 - Regio- and stereoselective hydrosilylation of terminal alkynes on solid support using diisopropyl hydrosilanes
yielding b-(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 phase 13C NMR and 1H high resolution magic angle spinning NMR.
