The unusual lability of the NN bond of the azobenzene ligand in [Fe2(CO)6(μ-Ph2N2)] (1) has allowed the insertion of SO2 under normal conditions. The resulting complex [Fe2(CO)6(μ-PhNSO2NPh)] (2) has been shown by structure determination to be a labilized sulphamide derivative. Thermolysis of 2 leads to elimination of SO2 and isolation of [Fe2(CO)6(μ-PhNCONPh)] (3), which is also a thermolysis
偶氮苯配体的NN键在的[Fe异常不稳定性2(CO)6(μ-PH 2 Ñ 2)](1)已经允许SO的插入2在正常条件下。通过结构确定已显示所得的络合物[Fe 2(CO)6(μ-PhN= SO 2 = NPh)](2)是一种迷雾化的磺酰胺衍生物。热解的2所导致SO消除2和隔离的[Fe 2(CO)6(μ-PhNCONPh)](3),这也是一个热解产物1。

The mu-E(2)R(2) bridged complexes Fe-2(CO)(6)(N(2)Ph(2)) (1a) and Fe-2(CO)(6)(P(2)(t)Bu(2)) (1b) undergo cluster expansion, with Fe-2(CO)(9) in hexane, to form the mu(3)-eta(2) bridged clusters Fe-3(CO)(9)(N(2)Ph(2)) (2a) and Fe-3(CO)(9)(P(2)(t)Bu(2)) (2b). Both clusters 2 are unstable in solution, being converted quantitatively with N-N or P-P cleavage into the bis-mu(3) bridged clusters Fe-3(CO)(9)(NPh)(2) (3a) and Fe-3(CO)(9)(P(t)Bu)(2) (3b) respectively.
