Abstract :Unsymmetric Organotin(IV) compounds of general formula R4-nSnR\primen have been synthesized by the reaction of corresponding organotin(IV) chlorides with n-hexyl magnesium bromide prepared in dry ether in situ, where R = CH3, n-C4H9, C6H5, C6H5CH2 and R\prime = n-C6H13. The reactions were carried out in dry toluene, refluxed for 6 h and the final products were purified through vacuum distillation. These compounds were characterized by multinuclear NMR (1H, 13C, 119Sn), IR spectroscopy and mass spectrometry to predict their structures. All spectroscopic results support the four-coordination and tetrahedral geometry of the compounds.
Keywords : Unsymmetric organotin(IV) compounds, multinuclear NMR, tetrahedral organotin(IV) compounds.
