文摘

The reaction of BiCl₃ with the lithium salt of o-di-tert-butylphenolunder nitrogen forms organic oxidation products rather than theexpected Bi(OAr)₃ complex, and bismuth disproportionation products. Likewise, the decomposition of Bi(III) aryloxides Bi(O-2,6-ⁱPr₂C₆H₃)₃ and ClBi(O-2,4,6-^tBu₃C₆H₂)₃ leads to corresponding organicoxidation products. These reactions can be explained by Bi-Obond homolysis to form unstable Bi(II) radicals, analogous to afundamental step suggested to intervene in the SOHIO process.
