Abstract

The direct sulfonation of arylphosphanes with H₂SO₄/SO₃/boric acid offers numerous advantages, the most significant being that P oxidation is largely avoided. In addition, selective sulfonation is possible. The products, for example 1, are water‐soluble and interesting with respect to two‐phase catalysis. Ar = C₆H₄‐m‐SO₃Na. (Figure Presented.)
