New phosphorus containing bis-sulfone ligands

Abstract

ABSTRACT.Derivatives of bis-sulfone 1,3-bis{(p-tolyl)SO2}-5-tertbutylbenzene 1, containing P(III) and P(V) were obtained and characterized in solution by multinuclear NMR spectroscopy. For two of the compounds ([2,6-{(p-tolyl)SO2}24-t-Bu-C6H2]PCl2 2 and [2,6-{(p-tolyl)SO2}24-t-Bu-C6H2]P(O)(H)OEt) 4 the crystal and molecular structures in solid state were also determined by single crystal X-ray diffraction.
