- Diverse structures and remarkable oxidizing ability of triarylbismuthane oxides. Comparative study on the structure and reactivity of a series of triarylpnictogen oxides
-
A systematic series of triarylbismuthane oxides was prepared in order to disclose their structure and reactivity, which have been compared with those of lighter pnictogen counterparts. X-ray crystallographic analysis of tris(2-methoxyphenyl)bismuthane oxide and tris(2-methoxyphenyl)stibane oxide revealed that they exist as dimers with a flat bis(a-oxo) ring, implying that the polarized Bi+-O- and Sb+-O- bonds aggregate to attain electrostatic stabilization. In sharp contrast to their phosphorus, arsenic, and antimony counterparts, triarylbismuthane oxides are thermally unstable and possess a high oxidizing ability. In particular, the bismuthane oxides bearing ortho-substituted aryl ligands oxidized primary and secondary alcohols to aldehydes and ketones, respectively, with high efficiency under mild conditions.

- A novel dry route to ortho-functionalized triarylbismuthanes that are difficult to access by conventional wet routes
-
When an aryl iodide bearing an electron-withdrawing group at the ortho position was milled together with bismuth shots and calcite grains in the presence of Cu powder and CuI using a laboratory ball mill, the corresponding orthofunctionalized triarylbismuthane was obtained in moderate to good yield.

- Stabilized bismuthonium ylides bearing a highly cross-conjugated ylidic carbon atom: Synthesis, structures, and reactions
-
The reaction of iminotriaryl-λ5-bismuthanes (2; Ar3Bi=NR; R = COR″ or SO2R″) with dialkyl acetylenedicarboxylates (3; R′O2CC≡CCO2R′) has been found to afford highly stabilized bismuthonium ylides (4;

- Unexpected formation of highly stabilized tetrakis-(2-alkoxyphenyl)bismuthonium salts in the oxidation of tris-(2-alkoxyphenyl)bismuthanes with iodosylbenzene
-
Treatment of tris-(2-alkoxyphenyl)bismuthanes 1 with iodosylbenzene in methylene dichloride at 40°C led to none of the expected bismuthane oxides 2 but, quite unexpectedly, gave tetrakis-(2-alkoxyphenyl)bismuthonium chlorides 3 in moderate to good yields. In some cases, bismuthonium formates 4 accompanied the main reaction products. Similar treatment in benzene in the presence of benzyl bromide, ethyl bromide, or 2,2,2-trifluoroethyl iodide led to the corresponding bismuthonium bromides 7 and iodides 8. Through anion exchange, a variety of bismuthonium salts including formate 4, tetrafluoroborate 11, toluene-p-sulfonate 12, bromide 7, iodide 8 and perchlorate 13 were prepared from the salt 3 in good yields. In contrast to the known tetraphenylbismuthonium salts, all of these new bismuthonium salts exhibited high thermal stability. The molecular structure of compound 7a was elucidated by X-ray analysis, where the four neighbouring oxygen atoms are found to surround the bismuth atom tetrahedrally via a weak through-space interaction with the metal, making the bismuth centre less susceptible to nucleophilic attack of the halide anion.
