N-BENZOIN-o-MERCAPTOANILINE AS AN EFFICIENT SYNTHON FOR ORGANOTIN(IV) COMPOUNDS

ABSTRACT

α-Benzoin reacted with o-aminothiophenol to give a diprotic ONS Schiff base H₂L. The preparation of organotin(IV) compounds of N-benzoin-o-mercaptoaniline via monoanion and dianion intermediates is reported. All of the newly synthesized compounds have been characterized by elemental analyses and spectral (IR,¹H,¹³C and ¹¹⁹Sn NMR) studies. Metal coordination occurs via deprotonation of the OH and SH groups, depending upon the reaction conditions.
