Resumen

Preparation of the neutral [Rh2(μ-sq)(COD)2] (1) (sq = squarate) and ionic [Rh(phen)(COD) (2) and [Rh(dppe)2]2[sq] (3) complexes is reported. Complex [Rh2(μ-sq) (CNR)4] (4) (R=p-tosylmethylisocyanide) has been prepared by substitution of the diolefinic ligands of complex 1. Carbonylation of compounds 1 and 2 gave [Rh2(μ-sq)(CO)4] (5) and [Rh(phen) (CO)2] [Rh(sq) (CO)2] (6), respectively. Compound [Rh2(μ-sq) (CO)2(PPh3)2] (7) was prepared by addition of PPh3 to complex 5. Complex 7 undergoes oxidative addition of molecular iodine leading to the rhodium (III) compound [Rh2(μ-sq) I4(CO)2(PPh3)2] (8).
