The reactive Bi(V)=N bond in (acylimiao)triaryl-lambda(5)-bismuthanes has been found to be stabilized effectively by ortho-substituted aryl ligands such as o-tolyl, o-anisyl, and mesityl groups, These imino-lambda(5)-bismuthanes, in which the bismuth center possesses a distorted tetrahedral geometry, behave-as ct nitrene precursor as well as an oxidizing agent, depending on the substrates and conditions.
