Abstract: Preparation of phosphabenzene compounds (A) by reacting the corresponding pyrilium salt (III) with phosphine, optionally in presence of solvent but without addition of acid catalyst or base. (III) and phosphine are contacted at about 0 degrees C then reacted at 0-200 degrees C at pressure over 1 bar. (A) have formulae (I) or (II); R -R = hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR, SR, 1-12C alkyl, 6-12C aryl, 7-12C aralkyl or alkaryl, or 3-6C heterocyclylalkyl with 1-3 heteroatoms, optionally substituted by the above groups, or two or more R groups together form a fused aliphatic ring; M = hydrogen, ammonium or alkali metal; X = anion; R = hydrogen or 1-6C alkyl; W = bridge comprising covalent bond, oxygen, sulfur, amino, di(1-6C)alkylsilyl or 1-16C residue that includes one or more linked cyclic or aromatic nuclei and optionally interrupted by 1-3 heteroatoms, and each o- or m-position on the phosphabenzene ring that is not bound to the bridge may be substituted by R -R .
