Nature of the Complexes of Benzoins with Group (IV) Halides

Department of Chemistry, Himachal Pradesh University, Simla-171001 Manuscript received 30 September 1973; revised 16 April 1974; accepted 24 April 1974 Benzoin (LH) forms compounds of composition MX3L with tetrachlorides and tetrabromides of tin and titanium and tetrachlorides of zirconium and silicon; compounds of composition SnI4LH in the case of tan tetraiodide while 2,2'-dichlorobenzoin and 2,2'-dinitrobenzoin form compounds of composition MX4LH at room temperature. On refluxing compontids of composition MX2L2 are obtained in the case of pure benzoic and of composition MX3L in the case of substituted benzoins. From conductance, molecular weight determination and i.r. spectral studidies, their structures have been elucidated.
