Organic Derivatives of Alkylene Dithiophosphates Part III: Synthesis and Properties of 2-( p -nitrophenyl) and 2-( p -nitrobenzoyl) Derivatives of Alkylene Dithiophosphates

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.
