Notes:
A stable hypervalent 10-Bi-4 species, tetraethylammonium bis[α,α-bis(trifluoromethyl)benzenemethanolato(2-)-C2],Obismuthanate(1-), was prepared by the reaction of bismuth trichloride with 2 equiv of lithium 2-(2-lithiophenyl)-2-propoxide derivatives. The ate complex was inert toward MeI, instead, the corresponding nonfluorinated analogue, bis[α,α-bis(dimethyl)benzenemethanolato(2-)-C2, O]bismuthanate(1-), was reactive enough toward MeI to give O-methylated product. Regioselective methylation at the nonfluorinated methanolate was observed in the reaction of unsymmetrically substituted ate complex, [α,α-bis(dimethyl)benzenemethanolato(2-)-C2, O[]α,α-bis(trifluoromethyl) benzenemethanolato(2-)-C2, O]bis-muthanate(1-). Mechanism of isomerization of these ate complexes and related protonated compounds and the synthesis and stability of [α,α-bis(trifluoromethyl)-benzenemethanolato (2-) -C2, O]diarylbismuthanate-(1-) were also described.
