Tetracyanooxirane oxidatively adds to rhodium(I) and iridium(I) species to afford metal(III) compounds. With trans-RhCl(CO)(PPh3)2 a reaction in boiling C6H6 produces RhCl(CN)(OC2(CN)3)(CO)(PPh3)2, a rhodium(III)(cyano)-(tricyanoenolato) compound. Characteristic frequencies are at 2225 (v(C-C≡N)), 2106 (v(Rh-C≡N)), 2009 (v(C≡0)), and 1620 cm−1 (v(C=C)). The nucleophilic trans-IrCl(CO)(PMe3)2 complex adds tetracyanooxirane at 25°C in THF to afford a stable oxametallacycle that shows a v(C≡N) band at 2199 and a v(C≡0) band at 2082 cm−1. The unsaturated MClP2 species (M = Rh, Ir; P = PPh3) decarbonylate terminal oxiranes (phenyl- and vinyloxirane) to give trans-MCl(CO)(PPh3)2 compounds.
