  Efficient One-Pot Synthesis of 2-Chloro-1,1, 1-trifluoro-2-alkenes Under Solvent-Free Conditions

  摘要：

  The improved one-pot Wittig reaction had been used to prepare trifluoromethyl-containing olefins under solvent-free conditions. Treatment of aldehydes with PPh3 and CF3CCl3 in the presence of K2CO3 at 100C afforded 2-chloro-1,1,1-trifluoro-2-alkenes in good to moderate yields.

  The catalytic olefination reaction of 2-nitrobenzaldehydes with CF3CCl3 afforded stereoselectively trifluoromethylated ortho-nitrostyrenes in up to 88% yield. The reaction of these alkenes with pyrrolidine permits preparation of α-CF3-β-(2-nitroaryl) enamines. Subsequent one pot reduction of nitro-group by Fe-AcOH-H2O system initiated intramolecular cyclization to afford 2-CF3-indoles. Target products

  Nucleophilic substitution reaction of halogen atom in β-chloro-and β-bromo-β-trifluoromethylstyrenes by thiolates was studied. Stereo-and regioselectivity of the reaction with respect to the electronic and sterical properties of substituents in the aromatic ring of starting styrenes was investigated. Regioisomer with geminal trifluoromethyl and alkyl-or arylthio groups was found to be formed predominantly or exclusively. The reaction proceeds stereoselectively in nearly quantitative yields. On this basis, a new convenient stereoselective method for the synthesis of trifluoromethylvinyl sulfides was elaborated.

  研究了β-氯和β-溴-β-三氟甲基苯乙烯中的卤素原子与硫醇的亲核取代反应。研究了反应的立体选择性和区域选择性与起始苯乙烯芳环上取代基的电子和立体性质的关系。发现该反应主要或只形成带有三氟甲基和烷基或芳硫基的区域异构体。该反应以接近定量的收率进行立体选择性反应。在此基础上，详细阐述了合成三氟甲基乙烯基硫化物的一种新的简便立体选择性方法。
