Many such reactions are now known, some being very rapid. The cleavage reaction of N20 on a 3-coordinate molybdenum amido species has been noted earlier (Section 1-3). Complexes of N20 will be considered later.

The reactions and nature of multiple bonds between two metal atoms form a lively area of research and debate (1,2). Many examples of triple bonds between metals are known, including the extensively studied molybdenum or tungsten alkoxide, M2(OR)6, and amido, M2(NR2)6, complexes (3). Classic examples of quadruple bonds are epitomized by [Re2Cl8]2 (4) and molybdenum acetate, Mo2(OCOMe)4 (5). 

The amido nitrosyl molybdenum complex MoCI(Tp )(NO)-(NH2)] reacts with alcohols, yielding the bisalkoxo complexes [Mo(OR)2(Tp )(NO)] (R = Me, Et, "Pr, Bu), analyzed by IR and H-NMR spectroscopy.60 Topaloglu and McCleverty also reported the synthesis and characterization of amido- and amido(monoalkylamido)-Mo(Tp )(NO) species61 and of [MoCl-(Tp )(NO)(OC6H4PPh 2-p)].62...

Internal proton transfer is observed for amido ligands. The reaction between the 1,2-dimethoxyethane adduct of trichloro(carbyne)molybdenum or -tungsten complexes and (trimethylsilyl)aiylamines produces the stable intermediates 20. The latter, however, re-...
