  Utilization of hypervalently activated organotin compounds in synthesis. Preparation and reactions of Me2N(CH2)3SnPh3

  摘要：

  The reaction of Me2N(CH2)3SnPh3 (1) with phenol gives Me2N(CH2)3Sn(OPh)nPh(3-n) (2, n = 1; 3, n = 2) in good yields. All the phenyl groups are cleaved off when 1 is treated with glycol or pinacol, resulting in the formation of [Me2N(CH2)3Sn]2(OC2H4O)3 (4) and [Me2N(CH2)3Sn]2(OC2Me4O)3 (5), respectively. Compounds 4 and 5 are transformed almost quantitatively into Me2N(CH2)3Sn(SPh)3 (6) and [Me2N(CH2)3SnCl4]-H+ (7) by reaction with phenyl mercaptan and trimethylchlorosilane, respectively. The reaction of 2 with triethanolamine and nitrilotriacetic acid affords the new stannatrane Me2N(CH2)3Sn(OCH2CH2)3N (8) and Me2N(CH2)3Sn(OCOCH2)3N (9), respectively. However, the N-oxide derivative Me2(O)N(CH2)3Sn(OCOCH2)3N (10) is obtained by reaction of 1 with N(CH2COOH)3 in DMF. Compounds 1-10 have been characterized by means of H-1, C-13 and Sn-119 NMR spectroscopy and mass spectrometry. The crystal structures of Me2N(CH2)3Sn(SPh)3 (6) and Me2(O)N(CH2)3Sn(OCOCH2)3N (10) have been determined by an X-ray diffraction study. The tin atom in 6 is trigonal bipyramidal with an intramolecular Sn-N distance of 2.605(6) angstrom. Compound 10 contains an octahedral tin with intramolecular Sn-N and Sn-ON distances of 2.231(7) and 2.101(7) angstrom, respectively.
