The direct sulfonation of arylphosphanes with H 2 SO 4 /SO 3 /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 = C 6 H 4 ‐ m ‐SO 3 Na.
