Abstract

Reactions of p -bromonitrobenzene and p -nitrobenzoyl chloride with ammonium salt of alkylene dithiophosphates {\\kern10pt}\\raise7pt\\hbox{{\\vrule height2pt width.5pt}{\\raise1.5pt\\hbox{\\vrule height.5pt width20pt}}{\\vrule height2pt width.5pt}}{\\kern-32pt} (OGOPS$_{\\hbox{\\scriptsize{\\it 2}}}\\begin{array}{@{}c@{}}\\\\[-17pt]\\hspace*{4pt}\\hbox{\\fontsize{6}{6}\\selectfont +}\\\\\\\\[-12pt]N\\end{array}H$\\hspace*{-2.5pt}$_{\\hbox{\\scriptsize{\\it 4}}}$ : G = --CMe 2 CMe 2 --, --CH 2 CMe 2 CH 2 --, --CMe 2 CH 2 CHMe--, --CH 2 CH 2 CHMe--) in 1:1 molar ratio in refluxing benzene solution yields: non-volatile yellow colored solids and red colored viscous liquids respectively of the type {\\kern10pt}\\raise7pt\\hbox{{\\vrule height2pt width.5pt}{\\raise1.5pt\\hbox{\\vrule height.5pt width20pt}}{\\vrule height2pt width.5pt}}{\\kern-32.5pt} OGOP(S)SR (R = --C 6 H 4 NO 2 , (O)CC 6 H 4 NO 2 ) which are monomeric in nature. The newly synthesized complexes have been characterized by physico-chemical and spectroscopic techniques (M.W., IR, NMR [ 1 H and 31 P]). On the basis of above studies, the formation of P--S--C and P--S--C(O) chemical bonds has been established.
