  摘要：

  Transmetallation of {eta(6)-1,4-(Bun3Sn)2C6H4}Cr(CO)2(PBun3) with nBuLi followed by treatment with diphenylchlorophosphine afforded as the major product {eta(6)-1,4-(PPh2)2C6H4}Cr(CO)2(PBun3) (4) and a minor amount of {eta(6)-1-(SnBun3)-4-(PPh2)C6H4}Cr(CO)2(PBun3) (5). Treatment of {eta(6)-1,4-(PPh2)2C6H4}Cr(CO)2(L) (9, L = CO; 4, L = PBun3) with [(CO)2RhCl]2 liberated carbon monoxide and gave the heterobimetallic coordination polymers {[eta(6)-1,4-(PPh)2C6H4]Cr(CO)2L]Rh(CO)Cl}n (10a, L = CO; 10b, L = PBun3). Coordination of both PPh2 substituents to rhodium led to hindered rotation about the Cr-(eta(6)-arene) axis (DELTA-G double-ended dagger = 11.7 +/- 0.1 kcal mol-1 for 10b, estimated from the P-31 DNMR spectra). The transmetallation chemistry was also used to prepare {eta(6)-(PPh2)C6H5}Cr(CO)2(L) (8a, L = CO; 8b, L = PPh3] in excellent yields.
