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.
