N=N Bond Cleavage by Tantalum Hydride Complexes: Mechanistic Insights and Reactivity.

A series of dinuclear tantalum(IV) hydrides [{TaCpRX2}2(mu-H)2] (CpR = eta5-C5Me5, eta5-C5H4SiMe3, eta5-C5HMe4; X = Cl, Br) show the ability to promote the N=N bond cleavage in their reactions with azobenzene and benzo[c]cinnoline in absence of reducing reagents. Both, characterization of intermedia...

Descripción
Sumario:A series of dinuclear tantalum(IV) hydrides [{TaCpRX2}2(mu-H)2] (CpR = eta5-C5Me5, eta5-C5H4SiMe3, eta5-C5HMe4; X = Cl, Br) show the ability to promote the N=N bond cleavage in their reactions with azobenzene and benzo[c]cinnoline in absence of reducing reagents. Both, characterization of intermediate species and DFT studies point to a mechanism in two stages, in which the Ta-Ta bond splitting is key for the reduction of the N=N bond and its complete scission.
