在BF_3·OEt_2存在下，三芳基铋(V)-氧代和-羟基化合物与有机硼酸和有机硼酸酯反应生成相应的铋盐。它们还与环状1，3-二羰基化合物进行脱水偶联。分别得到稳定的铋叶立德、铋N-酰亚胺和铋N-磺酰亚胺。所有反应在温和的条件下都能有效地进行。
Triarylbismuth(V)-oxo and -hydroxo compounds react with organoboronic acids and esters in the presence of BF 3 .OEt 2 to afford the corresponding bismuthonium salts. They also undergo dehydrative coupling with cyclic 1,3-dicarbonyl compounds. amides and sulfonamides to give stabilized bismuthonium ylides, bismuthane N-acylimides and bismuthane N-sulfonylimides, respectively. All reactions proceed efficiently under mild conditions.
