Abstract: The study of ionic tin compounds is current attention owing to their diversified molecular structure and wide range of application. Three kinds of ionic organotin compounds were obtained by the reaction of trialkyltin chloride and triphenyltin hydroxide with mercaptoacetic acid in the presence of organic bases. When Ph 3SnCl was treated with HSCH2COOH, a novel complex [Ph2ClSn (μ2-SCH2COO) ][R3NH] was formed with the cleavage of Ph—Sn and the dephenylation mechanism was proposed and approved by Ph 3SnOH treated with HSCH2COOH. All of the products were characterized by elemental analysis and 1H, 13C, 119Sn NMR. Antitumor activities of some compounds were tested for Bel-7402 and KB. The results show that the activities of compound B are better than compound A.
