The stepwise reaction of terminal alkynes with [(OC)Pt(mu-PBu2t)(2)Pt(H)((PBu2H)-H-t)]OTf yields intermediate eta(1)-alkynyl -hydride-bridged complexes, and then stable eta(1)-alkynyl/alkenyl-bridged derivatives containing an electrophilic carbonyl ligand. The latter is attacked by nucleophiles (H- and MeO-) to give a rare platinum formyl species, which is slowly converted into a stable hydride or a stable methoxycarbanyl complex.

Abstract
The stepwise reaction of terminal alkynes with [(OC)Pt(mu-PBu2t)(2)Pt(H)((PBu2H)-H-t)]OTf yields intermediate eta(1)-alkynyl -hydride-bridged complexes, and then stable eta(1)-alkynyl/alkenyl-bridged derivatives containing an electrophilic carbonyl ligand. The latter is attacked by nucleophiles (H- and MeO-) to give a rare platinum formyl species, which is slowly converted into a stable hydride or a stable methoxycarbanyl complex.File in questo prodotto:
