反応手順
Bis(4-methoxyphenyl)phenyl phosphine oxide (1.77 g, 5.2 mmol) and hydrobromic acid (31.0 g, 48%, 0.18 mol) were stirred at 123° C. for 21 h. The flask was fitted with a sodium sulfite scrubber for containment of methyl bromide. The reaction mixture was worked up to give the product as a tan powder (1.0 g, 62% yield). 31P NMR: (d6-DMSO) δ 27.9 (s).
