Abstract
AbstractThe cis‐[Rh(CO)2ClL] (1) complexes, where L = 2‐methylpyridine (a), 3‐methylpyridine (b), 4‐methylpyridine (c), 2‐phenylpyridine (d), 3‐phenylpyridine (e), 4‐phenylpyridine (f), undergo oxidative addition reactions with various electrophiles, like CH3I, C2H5I, C6H5CH2Cl or I2, to yield complexes of the types [Rh(CO)(COR)ClXL] (2) (where R = CH3 (i), C2H5 (ii), X = I; R = C6H5CH2 (iii), X = Cl) or [Rh(CO)ClI2L] (3) and [Rh(CO)2ClI2L] (4). The pseudo‐first‐order rate constants of CH3I addition with complexes 1 containing pyridine (g) and 2‐substituted pyridine (a and d) ligands were found to follow the order pyridine >2‐methylpyridine >2‐phenylpyridine. The catalytic activity of complexes 1 containing different pyridine ligands (a–g) on carbonylation of methanol was studied and, in general, a higher turnover number was obtained compared with that of the well‐known species [Rh(CO)2I2]−.
