Aryldiazenido (N2Ar) complexes. Carboxylate, formate, hydroxycarbonyl, and hydride derivatives of [(η-C5H5)Re(CO)2(N2Ar)][BF 4] and [(η-C5Me5)Re(CO)2(N2Ar)][BF 4]

The aryldiazenido complexes [(η-C5H5)Re(CO)2(p-N2C 6H4R)][BF4] (1: a, R = Me; b, R = OMe; c, R = NEt2) and [(η-C5Me5)Re(CO)2(p-N2C 6H4R)][BF4] (7, R = OMe) react with a stoichiometric amount of 0.1 M aqueous NaOH to give the air-stable, microcrystalline, golden yellow hydroxycarbonyl complexes (η-C5H5)Re(CO)(p-N2C6H 4R)(COOH) (2) and (η-C5Me5)Re(CO)(p-N2C6H 4R)(COOH) (8). These complexes dissolve in excess aqueous hydroxide to give bright yellow solutions of the respective carboxylate complex anions [(η-C5H5)Re(CO)(p-N2C6H 4R)(CO2)]- (4) and [(η-C5Me5)Re(CC)(p-N2C6H 4R)(CO2)]- (10), which have been isolated as lithium or calcium salts. Under specified conditions, which are discussed, decarboxylation occurs to yield the yellow hydride complexes (η-C5H5)ReH(CO)(p-N2C6H 4R) (3) and (η-C5Me5)ReH(CO)(p-N2C6H 4R) (9). Formate complexes (η-C5H5)Re(CO)(p-N2C6H 4R)(OCHO) (5) and (η-C5Me5)Re(CO)(p-N2C6H 4R)(OCHO) (11), isomeric with the hydroxycarbonyl complexes, have also been synthesized for comparison.
