  Synthesis of bulky tris[(dimethyl(alkyl/aryl)silyl)methyl]stannanes as radical based reducing agents

  摘要：

  The synthesis of novel bulky tris[dimethyl(ethyl/benzyl/p-tolyl/alpha-naphthyl)silylmethyl]stannanes (1-4) is described. Alkylation of SnCl4 with Me-2(ethyl/p-tolyl)SiCH2MgBr (10-11) gave mainly the triorganotin chlorides [(Me-2(ethyl/p-tolyl)SiCH2)](3)SnCl 14 and 15, which were isolated by silica gel chromatography. Reduction of 14 and 15 with LiAlH4 in THF gave the corresponding triorganotin hydrides 1 and 2, respectively. [Me-2(benzyl/alpha-naphthyl)SiCH2](3)SnCl 16 and 17, generated by the alkylation of SnCl4 with Me-2(benzyl/alpha-naphthyl) SiCH2MgBr 12 and 13, were inseparable from the minor product [Me-2(benzyl/alpha-naphthyl)SiCH2](2)SnCl2 18 and 19, respectively. Treatment of the mixtures of 16/18 and 17/19 with NaOH furnished the corresponding mixtures of stannoxanes, from which the hexakisdistannoxanes [Me-2(benzyl/alpha-naphthyl)SiCH2](6)Sn2O 20 and 22 were isolated from the minor dialkyltin oxide derivatives [Me-2(benzyl/alpha-naphthyl)SiCH2](2)SnO in good yields. Reduction of 20 and 22 with BH3 in THF gave [Me-2(benzyl/alpha-naphthyl)SiCH2](3)SnH (3 and 4), respectively in good yields. H-1, C-13, Sn-119, Si-29 NMR characteristics of the newly synthesized compounds are included. (C) 2011 Elsevier B. V. All rights reserved.
