Abstract
A practical and convenient synthesis of mono-, di- and a trisulfonated phosphines from triphenylphosphine analogs, (2,4-dimethylphenyl) 3− n -(phenyl) n -phosphine and (4-methoxyphenyl) 3− n -(phenyl) n -phosphine ( n=0–2), is described, respectively. This represents an easy way to prepare water-soluble phosphines with complete selectivity, and with essentially no phosphine oxide formation.
