Bis(silylene)-Stabilized Monovalent Nitrogen Complexes.

ABSTRACT: The first series of bis(silylene)-stabilized nitrogen(I) compounds is described. Starting from the 1,2-bis(N-heterocyclic silylenyl) 1,2-dicarba-closo-dedocaborane(12) scaffold 1, [1,2-(LSi)₂ C₂ B₁₀ H₁₀ ; L=PhC(N^t Bu)₂ ], reaction with adamantyl azide (AdN₃ ) affords the terminal N-μ₂ -bridged zwitterionic carborane-1,2-bis(silylium) AdN₃ adduct 2 with an open-cage dianionic nido-C₂ B₁₀ cluster core. Remarkably, upon one-electron reduction of 2 with C₈ K and liberation of N₂ and adamantane, the two silylene subunits are regenerated to furnish the isolable bis(silylene)-stabilized N^I complex as an anion of 3 with the nido-C₂ B
