Abstract

(CH,)(CO),(NO)(PPh,),(2) in good yields. Treatment of 2 with DC1 gives 1 and CHBD quantitatively. Reaction of 2 with carbon monoxide (2 atm, 80" C) results in a reversible substitution of CO for PPh3. to give mer-W (CH3)(C0),(NO)(PPh3)(3). Carbon dioxide undergoes a 1, Zinsertion reaction with 2 to give the monodentate acetate complex trans, tran~-W [~'-OC (0) CH~](C0)~(NO)(PPh~)~(4), which reversibly loses CO on heating to ...
