Abstract
A series of Rh-Mo and Ir-Mo compounds linked by a heterodifunctional ligand have been prepared. Li+[η5-C5H4P(C6H 4-p-CH3)2]Mo(CO)3 - (1) reacted with the chlorine-bridged rhodium dimer {[(C6H4-p-CH3)2PCH2] 2RhCl}2 (2) to give [(C6H4-p-CH3)2PCH2] 2RhMo(CO)3[η5-C5H 4P(C6H4-p-CH3)2] (3). Reaction of 1 with [(CO)2RhCl]2 gave (CO)2RhMo(CO)3[η5-C5H 4P(C6H4-p-CH3)2] (4). P(C6H4-p-CH3)3 or P(CH3)3 reacted with 4 to give phosphine substitution products trans-P(C6H4-p-CH3) 3(CO)RhMo(CO)3[η5-C5H 4P(C6H4-p-CH3)2] (5) and trans-P(CH3)3(CO)RhMo(CO)3-[η 5-C5H4P(C6H4-p-CH 3)2] (6), respectively. None of these rhodium-molybdenum compounds reacted with H2 to form observable metal hydrides. Reaction of 1 with (CO)2IrCl(H2NC6H4-P-CH3) provided iridium-molybdenum compound 8, (CO)2 IrMo(CO)3[η5-C5H4P(C 6H4-p-CH3)2]. Reaction of 8 with P(CH3)3 or P(C6H5)3 gave phosphine substitution products trans-P(CH3)3(CO)IrMo(CO)3[η 5-C5H4P(C6H4-p-CH 3)2] (9) and trans-P(C6H5)3(CO)IrMo(CO) 3[η5-C5H4P(C6H 4-p-CH3)2] (10), respectively. Compounds 8, 9, and 10 reacted readily with H2 at room temperature and atmospheric pressure to give Mo-IrH2 compounds 11, 12, and 13.
