Unusual chemical behaviour of silylated 1,2-dithiins under Lewis acid conditions
摘要:
Different silylated 1,2-dithiins, obtained through self-dimerization of the related alpha,beta-ethylenic thioacylsilanes, in the presence of AlCl3 show an unusual rearrangement leading in good yields to novel silyl-endodisulfide bicyclic systems. (c) 2005 Elsevier Ltd. All rights reserved.
An easy access to α,β-unsaturated thioacylsilanes: a useful route to silylated 1,2-dithiins
摘要:
Treatment of different silylated allenes with hexamethyldisilathiane (HMDST) in the presence of CoCl2.6H(2)O affords an easy and high yielding access to alpha,beta-unsaturated thioacylsilanes, which undergo a self-dimerization reaction to afford polyfunctionalized 1,2-dithiins as the major products.
