Reaction of 6-Bromo-1,2-naphthoquinone with Tertiary ortho-Anisylphosphines as a Convenient Synthetic Approach to 1,2-Dihydroxynaphthylphosphonium Salts

A mild and effective method for the synthesis of new tetraarylphosphonium zwitterions and salts containing methoxy and hydroxy groups in aryl substituents at the phosphorus atom was developed. The structure of phosphorus-containing betaines and phosphonium salts was obtained by NMR spectroscopy.
