  Combinative use of high-pressure, metal-templating and sulfur-nucleophilicity towards dithiacyclophane synthesis and its complex intermediates

  摘要：

  Combined use of elevated pressure in the liquid phase (15 kbar), a metal template and the sulfur nucleophilicity of [Pt-2(mu-S)(2)-(P-P)(2)] (P-P = diphosphine or 2 (.) monophosphine) facilitates the one-pot synthesis of 3,8-dibenzo-1,6-dithiacyclodecane. Under r.t.p., nucleophilic addition of [Pt-2(mu-S)(2)(P-P)(2)] [P-P = 2 (.) PPh3; Ph2P(CH2)(n)PPh2, n = 2, 1,2-bis(diphenylphosphino)ethane (dppe), 3, 1, 3-bis(diphenylphosphino)propane (dppp)] with alpha-alpha'-dichloro-o-xylene would terminate as a dithiolato bridged cation viz. [PtAvSCH(2)C(6)H(4)CH(2)S)(P-P)(2)](2+). Under high pressure (15 kbar) at r.t., these stoichiometric reactions progress via a "catalytic-like" pathway to yield 3,8-dibenzo-1,6-dithiacyclodecane (up to 35%), and a series of mechanistically relevant intermediates and byproducts. The dithiolated intermediates [Pt-2(mu-SCH2C6H4CH2S)(P-P)(2)](2+) for PPh3 and dppp have been isolated as PF6 complexes and their crystal structure determined. The formation of 3,8-dibenzo-1,6-dithiacyclodecane demonstrates a convenient Synthetic strategy over the multi-step synthesis of this macrocyclic dithioether. (c) 2005 Elsevier B.V.
