  Preference of di-n-butyltinIV compounds to build O⋯Sn bonds in fused rings with five-six members

  摘要：

  The reaction of salicylaldehyde (1), o-aminophenols (2a-2f), and di-n-butyltin(IV) oxide (3) to give six di-n-butyltin(IV) compounds (4a-4f) was achieved in good yields. All compounds were characterized by H-1, C-13, N-15, Sn-119 NMR, mass spectrometry, IR, elemental analysis and in the case of compounds 4a, 4b, 4d and 4e by X-ray diffraction analysis. Compound 4a crystallized with trigonal bipiramidal (TPB) geometry surrounding the tin atom while 4b and 4e crystallized as dimeric molecules joined by two (OSn)-Sn-... bonds with distorted octahedron (DOC) geometry. The X-ray structure of 4d presents one cocrystallized monomeric TBP with one dimeric DOC molecule. Correlations of sigma(Hammett) vs. spectroscopic values were found for 4a-4b and 4d-4f, indicating the substituents in the aromatic ring derived from o-aminophenol serve as modulators of the (OSn)-Sn-... supramolecular interaction. The (OSn)-Sn-... bond formation is selective for the five-membered ring oxygen atom. (C) 2004 Elsevier B.V. All rights reserved.

• Synthesis, Spectroscopic and Polarographic Studies of Dibutyltin(IV) Complexes of Schiff Bases Derived from 2-Aminophenol

  A series of dibutyltin(IV) complexes of Schiff bases derived from 2-aminophenol and benzaldehyde (HL1), anisaldehyde (HL2), 2-furfural (HL3), acetophenone (HL4), benzylmethyl ketone (HL5), benzil (HL6), salicylaldehyde (H2L7), 2-hydroxy-1-naphthaldehyde (H2L8) and 2-hydroxyacetophenone (H2L9) have been synthesized by the reaction of dibutyltin(IV) oxide with the preformed Schiff bases in 1:1 or 1:2 molar ratios in benzene with azeotropical removal of water. The analytical data are in agreement with the proposed stoichiometries of the complexes. Molar conductance values of the complexes (10(-3) M) in methanol indicate their non-electrolytic nature. Cis-trigonal bipyramidal or trans-octahedral geometries have been proposed for the complexes Bu2SnL2 (where HL = HL1 to HL6) and Bu2SnL (where H2L = H2L7 to H2L9), respectively, on the basis of electronic, infrared, far-infrared, H-1, C-13 and Sn-119 NMR, and Sn-119 Mossbauer spectral studies. All the Schiff bases and their dibutyltin complexes undergo reduction in the range -0.28 V to -2.5 V and their polarographic reduction is diffusion controlled and irreversible.
