Abstract
Abstract12‐Chloro‐12‐n‐butyl‐1,11‐dioxa‐4,8‐ dithia‐12‐stannacyclododecane (3a) and 12‐chloro‐ 12‐n‐butyl‐1,4,8,11‐tetrathia‐12‐stannacyclododecane (3b) have been prepared by reacting n‐butyltin trichloride with 1,11‐dioxa‐4,8‐dithiaundecane and 1,4,8,11‐tetrathiaundecane, respectively. Complexes 3a,b were characterized by elemental analyses, IR, electron impact mass spectrometry, and multinuclear NMR (1H, 13C, and 119Sn). The spectroscopic data are consistent with bonding of the ligands through both sulfur and oxygen atoms in 3a and through all sulfur atoms in 3b to the Sn(IV) center. We suggest hexacoordination around the Sn atoms. © 2004 Wiley Periodicals, Inc. Heteroatom Chem 15:451–453, 2004; Published online in Wiley InterScience (www.interscience.wiley.com).
