Y. Matano et al., First synthesis, structure, and reactivity of (acylimino)triaryl-lambda(5)-bismuthanes stabilized by ortho-substituted aryl ligands, ORGANOMETAL, 18(14), 1999, pp. 2580-2582
The reactive Bi(V)=N bond in (acylimiao)triaryl-lambda(5)-bismuthanes has b
een found to be stabilized effectively by ortho-substituted aryl ligands su
ch as o-tolyl, o-anisyl, and mesityl groups, These imino-lambda(5)-bismutha
nes, in which the bismuth center possesses a distorted tetrahedral geometry
, behave-as ct nitrene precursor as well as an oxidizing agent, depending o
n the substrates and conditions.
