Description |
Reaction of dimeric complex [Rh(CO)2Cl]2 with two molar equivalent of pyridine alcohol ligands (L) like
2-hydroxymethylpyridine (a), 3-hydroxymethylpyridine (b) and 4-hydroxymethylpyridine (c) afford the
rhodium(I) dicarbonyl complexes [Rh(CO)2ClL](1a–c). The ligands are coordinated to the metal center
through N-donor site. The complexes 1 undergo oxidative addition (OA) reactions with various alkyl
halides (RI) like CH3I, C2H5I to produce Rh(III)complexes of the type [Rh(CO)(COR)IClL], where R = –CH3(2),
–C2H5(3). Kinetic data for the reaction of 1 with CH3I indicate a first order reaction. The catalytic activity
of the complexes 1 in the carbonylation of methanol was higher than that of the well known species
[Rh(CO)2I2]−.
