Redox-Neutral Organometallic Elementary Steps at Bismuth: Catalytic Synthesis of Aryl Sulfonyl Fluorides

A Bi-catalyzed synthesis of sulfonyl fluorides from the corresponding (hetero)aryl boronic acids is presented. We demonstrate that the organobismuth(III) catalysts bearing a bis-aryl sulfone ligand backbone revolve through different canonical organometallic steps within the catalytic cycle without modifying the oxidation state. All steps have been validated, including the catalytic insertion of SO2 into Bi-C bonds, leading to a structurally unique O-bound bismuth sulfinate complex. The catalytic protocol affords excellent yields for a wide range of aryl and heteroaryl boronic acids, displaying a wide functional group tolerance.

LIVING RADICAL POLYMERIZATION PROMOTER

An organobismuth compound represented by the formula (1) and a method for preparing a living radical polymer using the organobismuth compound. In the formula (1), R1 to R3 each represent a C1-C8 alkyl group, an aryl group, a substituted aryl group, an aromatic heterocyclic group or a group represented by the formula (2) where at least one of R1 to R3 is a group represented by the formula (2), wherein R4 and R5 each represent a C3-C8 alkyl group, an aryl group or a substituted aryl group, and R6 to R8 each represent a hydrogen atom, a C1-C8 alkyl group, an aryl group or a substituted aryl group.

Synthesis and structure of pentavalent bismuth(V) alkoxides and ligand redistribution equilibria in solution

The six new pentavalent Bi(V) alkoxide complexes Ph3Bi(OR)2, 1, Ph3BiBr(OR), 2, and Ph4Bi(OR), 3 (a, R = C6F5; b R = C6Cl5) have been prepared. Ph4Bi(OR) was synthesized by alcoholysis of BiPh5 with ROH. Ph3Bi(OR)2 and Ph3BiBr(OR) were products of the salt elimination reaction between Ph3BiBr2 and NaOR. These compounds were characterized spectroscopically and by single-crystal X-ray diffraction. In the solid state, they possess distorted trigonal bipyramidal coordination geometries. Although the mixed species Ph3BiBr(OR) may be isolated in pure form as crystalline solids, they do not exist as pure compounds in solution owing to the very rapid redistribution equilibrium Ph3Bi(OR)2 + Ph3BiBr2 ? 2Ph3BiBr(OR). The equilibrium constants were measured using VT NMR spec-troscopy. For comparison, the equilibrium constants for the previously unreported cross-exchange reactions between the dihalides Ph3BiX2 (X = F, Cl, Br) were also measured at 226 K. Trends observed in the values of Keq correlate with the difference in the electro-negativity of the mixed X species. The thermal stabilities of Ph3Bi(OR)2 were examined in toluene solution and in the solid state. Pyrolysis results in elimination of ROPh for both R = C6F5 and C6Cl5.
