The kinetics of the addition reactions of tetracyanoethylene (TCNE), dimethyl maleate (DMM), diethyl maleate (DEM), maleicanhydride (MA), acetylenedicarboxylic acid (ADCA) and dimethyl acetylenedicarboxylate (DMADC) to complexes of the type trans‐{Ir(CO)XL 2 } (X = Cl, Br, I; L = P(C 6 H 5 ) 3 , P(p‐CH 3 C 6 H 4 ) 3 , P(p‐CH 3 OC 6 H 4 ) 3 , P(OC 6 H 5 ) 3 ) in various solvents were investigated employing stopped‐flow techniques. The kinetics were found to obey a second order/first order rate law for a reversible process. The rate constants obtained are discussed in terms of a Lewis acid‐base model.
