摘要
The reactions of 8-methoxyquinoline (C10H9ON) with R2SnCl2 (R = Ph, Me, n-Bu) have been investigated. All these reactions yielded the corresponding distannoxanes, [(R2SnCl)(2)O](2), 8-methoxyquinolinium chloride for R = n-Bu and organostannate salts for R = Ph, Me. The central tin atom of the stannate salts is not bonded to the two N and O donor atoms of the ligand species. X-ray structural analysis was performed on the complexes, [C10H9ON . H . NOH9C10]Ph2SnCl3 and [C10H9ON . H](2)Ph2SnCl4, and the results along with those obtained from a variety of physical measurements for these products are discussed. In addition, it was found that the Ph2SnCl3- moiety present in [C10H9ON . H . NOH9C10]Ph2SnCl3 disproportionated into Ph2SnCl2 and Ph2SnCl42-. (C) 1998 Elsevier Science S.A. All rights reserved.
