trans-(Ph3P)2Ir(CO)Cl and trans-(Ph2PMe)2Ir(CO)Cl rapidly undergo oxidative-addition reactions with trifluoroacetyl cyanide affording the crystalline complexes L2Ir(CO)Cl[CF3COCN](L = Ph3P or Ph2PMe). The related rhodium complex (Ph2PMe)2Rh(CO)Cl[CF3COCN] is obtained from trans-(Ph2PMe)2Rh(CO)Cl. Spectroscopic studies suggest that the complexes are best depicted as trifluoroacetyl cyanide adducts of iridium(III) and
化合物反式- (PH 3 P)2的Ir(CO)Cl和反式- (PH 2 PME)2的Ir(CO)氯迅速经历与三氟乙酰基氰化物氧化加成反应得到的结晶复合物大号2的Ir(CO)氯[ CF 3 COCN](L = Ph 3 P或Ph 2 PMe)。从反式-(Ph 2 PMe)2 Rh(CO)Cl获得相关的铑配合物(Ph 2 PMe)2 Rh(CO)Cl [CF 3 COCN] 。光谱研究表明,该配合物最好被描述为铱的三氟乙酰基氰化物加合物(III)和铑(III),其中配体羰基的碳原子和氧原子都与金属原子键合。此外,膦配体在铱加合物中具有反式构型,而它们在铑络合物中具有相对的顺式构型。
