Ammonium and potassium salts featuring the chiral mer-[P(C6H4CO2)3]−, mer-[1]−, have been isolated. Specifically, treating phosphorane P(C6H4CO2)2(C6H4CO2H), 2, with N-containing bases [Nbase = PhNMe2, PhNH2, pyridine (py), isoquinoline, (−)-brucine, N(n-C8H17)3] afforded ammonium salts [NbaseH]+-mer-[1]−. Each compound was fully characterized spectroscopically, and four were subjected to X-ray crystallographic analysis.

Treating PCl with C H Li , generated from either C H , C H Br , or C H I , affords three products in different ratios depending on the source of the lithiated biphenyl.

The development of solid, weighable Brønsted acids featuring the hexacoordinated phosphorous( ) anion [TRISPHAT] are reported. H(DMF) [1] and H(THF) [1] {[1] = [P(1,2-O C Cl ) ] } were synthesized and fully characterized by H, P, C and 2D-NOESY NMR spectroscopy, X-ray crystallography, mass spectrometry and elemental analysis. Both, H(DMF) [1] and H(THF) [1] are found to be suitable initiators for the polymerization of n-butyl vinyl ether and p-methoxystyrene.
