Synthesis and structures of intramolecularly hexacoordinated organotin chlorides containing the (3-(2-methoxy)ethoxy) propyl moiety
摘要:
Two water-soluble organotin compounds, (3-(2-methoxy)ethoxy)propyltin trichloride, 1, and bis (3-(2-methoxy)ethoxy)propyltin dichloride, 2, were synthesized and characterized by (1)H, (13)C and (119)Sn NMR spectroscopy and by X-ray diffraction. In both cases, the geometry at the tin atom is that of a distorted cis-octahedron, which is preserved for both compounds in CDCl(3) solution. A detailed solution structure is proposed for 1 from 1D (1)H-(119)Sn HMQC NMR experiments. (C) 1997 Elsevier Science S.A.
