Insertion of carbon dioxide and of unsaturated carbon compounds into the platinum–nitrogen bond: the X-ray crystal structure of Pt{ON(Ph)C(O)O}(PPh3)2
Abstract
Pt(PhNo)(PPh3)2 reacts with unsaturated carbon compounds such as carbon dioxide, carbon disulphide, alkenes, and dimethyl acetuylenedicarboxylate to give 1:1 adducts; X-ray studies on the adduct formed with carbon dioxide, [graphic omitted]}(PPh3)2, show that the entering molecule is inserted into the platinum–nitrogen bond of the η2-bonded nitroso ligand.
