The iridium(I) complexes 1)(L2)2> (L1 = CO or N2) react with peroxycarboxylic acid, RCO3H, to give the carboxylato-complexes 2)2> (X = Cl, R = 3-ClC6H4, L2 = PPh3, PPh2Me, or AsPh3; X = Cl, R = Ph, L2 = PPh3 or AsPh3; X = Cl, R = Me, L2 = PPh3; X = BR, R = 3-ClC6H4, L2 = PPh3) with evolution of carbon dioxide; the compounds (X = Cl, L2 = PPh3, R = Me, Ph, or 3-ClC6H4) have also been obtained from and diacyl peroxides.The iodo complex behaves anomalously giving with RCO3H (R = Ph or 3-ClC6H4), and a mixture of and with dibenzoyl peroxide.Diacyl peroxides, (RCO2)2, react with to give the complexes (R = Ph or 3-ClCH64) in high yields, and the compound where R = Ph rather than the expected is formed under similar conditions with acetyl peroxybenzoate.The palladium(0) complexes (L = PPh3 or 1/2 Ph2PCH2CH2PPh2) react to form with dibenzoyl peroxide at room temperature, but (M = Pt or Pd) and do not react under these conditions.Similarly, there is no reaction between and the peroxy-ester ButO2C(O)Ph at room temperature, but and give and respectively as the only metal-containing products.

The stable complexes 2Cl(CO)L2> (L= PPh3, AsPh3, or PMePh2) and 2(PPh3)> have been prepared by oxidative addition of the radical (CF3)2NO. to trans- and either 2-C2H4)(PPh3)2) or respectively.The compounds trans- (X = Br or l) react with the radical to give a mixture of 2>(PPh3)2> and .The platinum(II)complexes 2L2> (L= PPh3, AsPh3, or PMePh2) and the gold(I) complex (PPh3)>have been synthesized by metathetical exhange of the chlorine atoms in cis- and using2>.The weak nucleophile Na has been shown to react with the complexes ClO4 (M = RH or lr) to give the compounds trans-(CO)(PPh3)2>, while reaction with the complexes trans-BF4 (X = Cl, L = PPh3 or AsPh3; X = Br, L = PPh3) occurs at the carbonyl ligand giving L2>.The new iridium(I) complex trans-(CO)(PPh3)2> forms an oxygen comple in solution, and reacts with halogens, CF3CO2H, HgCl2 and C6H5CH2COCl to give the products (X= Cl or I), , respecyively, with loss of the (CF3)2NO ligand; unstable oxidative-addition products (R)I(CO)(PPh3)2> (R = CF3, CH3, or C2H5) have been characterized from the reactions with iodoalkanes.
