Reaction Steps

Bis(4-methoxyphenyl)-tert-butylphosphine oxide mixture (25.0 g), hydrobromic acid (770 g, 48%), and potassium bromide (30.0 g) were stirred for 25 h at 120° C. The flask was fitted with a sodium sulfite scrubber for containment of methyl bromide. The reaction mixture was worked up to give a tan solid (9.6 g, 40%). 31P NMR (d6-DMSO): δ 46.3 (s, 31.8%), 39.6 (s, 31.7%), 28.7 (s, 20.4%), −8.2 (s, 16.1%).
