platinaoxetanes are inert to CO2. Treatment of 1 with tetracyanoethylene (TCNE) yields Pt(COD)(TCNEOC7H10) (7) by alkene insertion into the Pt−O bond, while 1 shows no reactivity with ethylene or isobutylene. Similarly 1 reacts with diethylacetylenedicarboxylate (DEAD) to give a rare alkyne M−O bond insertion product Pt(COD)(DEADOC7H10) (8) but is inert to diphenylacetylene. Reaction of 1 with isocyanide in a
