Treatment of hydrated RhCl3 and Cu(NO3)2 in THF and H2O with triethoxysilane affords a highly chemo- and stereoselective catalyst system for the reduction of alkynes to Z-alkenes while alkyl-NO2, aryl-NO2, N-carbobenzyloxy, hydroxy, ester, enoate, benzyloxy, alkyl bromide, aryl bromide, and enone moieties remain unaffected.
