摘要：

The syntheses of the intramolecularly coordinated organotin compounds {Me2N(CH2)(3)}Ph(X)SnCH2SnPh2X (3, X = I; 4, X = F) and {Me2N(CH2)(3)}Ph(F)Sn(CH2)(3)SnPh2F (7) are reported. The compounds have been characterized by elemental analysis, electrospray mass spectrometry, H-1,H-1 DOSY (4), C-13, F-19, and Sn-119 NMR spectroscopy, and single-crystal X-ray diffraction analysis. In the solid state, compound 4 is a head-to-tail dimer as a result of unsymmetrical Sn-F-Sn bridges, whereas compound 7 is a monomer with F -> Sn intramolecular coordination, giving a six-membered ring. In solution, both 4 and 7 are monomeric. The reactions of both 4 and 7 with fluoride anion temperature F-19 and Sn-119 NMR spectroscopy.
