title: Nitric oxide insertion reactivity with the bismuth-carbon bond: formation of the oximate anion, [ON=(C6H2tBu2O)]-, from the oxyaryl dianion, (C6H2tBu2O)2-.
abstract: The first example of NO insertion into a Bi-C bond has been found in the direct reaction of NO with a Bi(3+) complex of the unusual (C6H2tBu2-3,5-O-4)(2-) oxyaryl dianionic ligand, namely, Ar'Bi(C6H2tBu2-3,5-O-4) [Ar' = 2,6-(Me2NCH2)2C6H3] (1). The oximate complexes [Ar'Bi(ONC6H2-3,5-tBu2-4-O)]2(μ-O) (3) and Ar'Bi(ONC6H2-3,5-tBu2-4-O)2 (4) were formed as a mixture, but can be isolated in pure form by reaction of NO with a Bi(3+) complex of the [O2C(C6H2tBu2-3-5-O-4](2-) oxyarylcarboxy dianion, namely, Ar'Bi[O2C(C6H2tBu2-3-5-O-4)-κ(2)O,O']. Reaction of 1 with Ph3CSNO gave an oximate product with (Ph3CS)(1-) as an ancillary ligand, (Ph3CS)(Ar')Bi(ONC6H2-3,5-tBu2-4-O) (5).
