Study of homo- and cross-coupling competition in the reaction of triarylbismuth(V) dicarboxylates with methyl acrylate in the presence of a palladium catalyst

Triarylbismuth(V) derivatives Ar3Bi(O2CR)2 (Ar = Ph, m-Tol, p-Tol; R = H, Me, Et, n-Bu, t-Bu, n-C5H 11, CF3, CH2Cl, CCl3, Ph) were prepared in good to excellent yields by reaction of Ar3Bi with equimolar amounts of t-BuOOH in the presence of an acid. These compounds were tested in the C-arylation reaction of methyl acrylate, as a model substrate, in the presence of palladium catalyst (4 mol%). It was found that triphenylbismuth dicarboxylates are very active phenylating agents under mild conditions (20 °C). The effect of the carboxylic group, the effect of the nature of the palladium catalyst and the effect of oxygen on the reactivity of the organobismuth compounds and on the selectivity of the C-arylation reaction were studied. Methyl cinnamate, the C-phenylation product, and biphenyl, the homo-coupling by-product, were obtained in all cases. Triphenylbismuth divalerate Ph3Bi(O2CBu)2 is the most reactive compound among the triphenylbismuth dicarboxylates studied.

Synthesis, structure and reactions of μ- oxobis(arenesulfonatotriarylbismuth)

Hydrolysis of triarylbismuth bis(arenesulfonates) in acetone gives bismuth derivatives of the general formula [Ar3Bi(OSO2Ar')] 2O (Ar = Ph, p-Tol; Ar' = Ph, C6H4Me-4, C 6H3Me2-2,4, C6H3Me 2-3,4). The structure of μ-oxobis[(3,4-dimethylbenzenesulfonato) triphenylbismuth] was established by means of X-ray diffraction. The molecule has a linear centrosymmetric structure with the bridging oxygen atom in the inversion center. The bismuth atom has a distorted trigonal bipyramidal coordination with the bridging oxygen atom and the arenesulfonate group in axial positions. The Bi-C and Bi-Oterm distances are 2.200(2), 2.204(3), and 2.442(2) A, and the Bi-Obr distances are 2.067(1) A. 2004 MAIK "Nauka/Interperiodica".

Reaction of pentaphenylantimony with triphenylbismuth diacylates

Reactions of pentaphenylantimony with triphenylbismuth diacylates yield the corresponding tetraphenylantimony acylates. Triphenylbismuth bis(trichloroacetate) was prepared by oxidation of triphenylbismuth with hydrogen peroxide in the presence of trichloroacetic acid. The structure of triphenylbismuth dibenzoate was determined by single crystal X-ray diffraction. The coordination polyhedron of the central atom is intermediate between trigonal bipyramid and pentagonal bipyramid; the benzoate groups occupy the equatorial position.

A novel synthesis of triarylbismuth dihaloacetates

Triarylbismuth dihaloacetates were prepared in good yields through carboxylic group - transformation. The method had advantages of simple manipulation, nonusage of silver salt and mild conditions.
