Phenylbismuth bis(2,5-dimethylbenzenesulfonate) (I), a coordination polymer in which a bis-muth atom has a distorted square pyramidal coordination to an axial carbon atom (Bi-C, 2.247(5) A?) and basal oxygen atoms (Bi-O, 2.390(9)-2.403(10) A?), has been synthesized by the reaction between triphenyl- bismuth and 2,5-dimethylbenzenesulfonic acid (1 : 2 mol/mol) in toluene and structurally characterized. Pentaphenylbismuth and pentaphenylantimony phenylate compound I to triphenylbismuth.

Reactivity of TerN(SiMe3)BiCl2 - Synthesis of an Aminobismuthenium Cation and TerN(SiMe3)Bi(N3)2

, p. 2571 - 2580 (2018)
The reaction of TerN(SiMe3)BiCl2 (1) (Ter = 2,6-bis(2,4,6-trimethylphenyl)phenyl) with Lewis acids such as GaCl3 and Ag[OTf] (OTf = OSO2CF3) was studied. While the reaction of 1 with GaCl3 led to decomposition into bismuth black, TerNH2·GaCl3, and [TerNH3][GaCl4], the reactions of 1 with 1 and 2 equiv of Ag[OTf] resulted in methyl/triflate exchange reactions affording TerN(SiMe2OTf)Bi(Me)Cl (2) and TerN(SiMe2OTf)Bi(Me)OTf (3). To circumvent the methyl/triflate exchange, the diiodide compound TerN(SiMe3)BiI2 (5) and the azide-substituted derivatives TerN(SiMe3)Bi(Cl)N3 (6) and TerN(SiMe3)Bi(N3)2 (7) were prepared, although it was not possible to isolate pure 7 because of small impurities of 6. All of the bismuth compounds (1-7) were characterized by single-crystal X-ray diffraction and NMR, IR, and Raman spectroscopy. According to quantum-chemical calculations, 3 can be regarded as a donor-stabilized aminobismuthenium cation with OTf- as the counterion. As expected for bismuth compounds with aromatic scaffolds, Bi···-arene interactions were observed. The influence of the substitution at the bismuth atom on the strength of this intramolecular interaction with the terphenyl moiety was studied by experimental (crystal structures) and theoretical methods. A correlation between the Lewis acidity (NBO charge) and the Bi···-arene distance could be established.

, p. 725 - 733 (2015)
Two new homo- and heteroleptic bismuth thiazole-thiolato complexes derived from 4-phenylthiazole-2-thiol MBT(H) have been synthesised and structurally characterised, [BiPh(MBT)2]2 and [Bi(MBT)3]2. Syntheses were achieved using BiPh3 or Bi(OtBu)3 in protolysis reactions with MBT(H), or by salt metathesis with BiCl3 or BiPhCl2 and the sodium thiolate, [NaMBT]. The complexes were obtained under both standard solvent-free and solvent-mediated conditions, and by microwave irradiation. The solid-state structures of [BiPh(MBT)2]2 and [Bi(MBT)3]2, were determined using single-crystal X-ray diffraction, showing them to be dimeric. The bactericidal properties of the complexes against Mycobacterium smegmatis, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Enterococcus faecalis, vancomycin-resistant Enterococcus (VRE) and Escherichia coli revealed [BiPh(MBT)2]2 to be the most effective against all the bacteria with MIC values of 0.6 μg/mL (0.25 μM) against S. aureus and 0.9 μg/mL (0.27 μM) against E. faecalis. [Bi(MBT)3]2 was less active overall. However, comparisons with the analogous complex [Bi(4-BrMTD)3], revealed a significant hundred-fold enhanced activity against S. aureus, MRSA, VRE, and E. faecalis. Both complexes showed little or no toxicity towards mammalian COS-7 cells at 20 μg/mL. [BiPh(MBT)2]2 also was found to display good antileishmanial activity with an IC50 value of 0.11 μg/mL (0.17 μM), at which concentration the complex was non-toxic to human fibroblast cells.

Investigation into the Organobismuth Dismutation and Its Use for Rational Synthesis of Heteroleptic Triarylbismuthanes, Ar12Ar2Bi

supporting information, (2020/03/16)
Organobismuthanes undergo dismutation, a substituent scrambling process, complicating the synthesis of unsymmetrically trisubstituted bismuthanes of the general formula Ar12Ar2Bi. Although the dismutation is a mechanistically diverse phenomenon, at ambient or lower temperatures, dismutation is triggered mainly by an electrophilic bismuth source. Therefore, the selection of the electrophile, Ar12BiX (X = tosylate or iodide if Ar1 = mesityl) or Ar1BiX2 (X = tosylate), and its use in low concentration during the reaction is key to suppressing the dismutation, leading to new, streamlined protocols utilizing direct arylations of Ar12BiX (X = OTs or I) or Ar1Bi(OTs)2 with organozincs affording heteroleptic triarylbismuthanes Ar12Ar2Bi.
