  Palladium-Catalyzed Trifluoroethylation of Terminal Alkynes with 1,1,1-Trifluoro-2-iodoethane

  摘要：

  An efficient C-sp-CH2CF3 bond-forming reaction via Pd-catalyzed 2,2,2-trifluoroethylation of aryl and alkyl terminal alkynes has been developed. This protocol proceeds under mild conditions using the readily available and cheap reagent CF3CH2I as the source of the CH2CF3 group. Various terminal aryl alkynes as well as alkylacetylenes can be transformed Into the corresponding trifluoroethylated products In good-to-excellent yields. The method is tolerant of carbonyl, nitro, ester, cyano, and even formyl groups.

  A trifluoroethylation of alkynes through a palladium-catalyzed decarboxylative coupling reaction was developed. When alkynyl carboxylic acids and ICH2CF3 were allowed to react with [Pd(η3-allyl)Cl]2/XantPhos and Cs2CO3 in N,N-dimethylformamide (DMF) at 80 °C for 1 h, the desired products were formed in good yields. This catalytic system showed high functional group tolerance.

  通过钯催化的脱羧偶联反应，开发了炔烃的三氟乙基化反应。当炔基羧酸和ICH 2 CF 3被允许通过[加入Pd（η反应3 -烯丙基）CL] 2 / XANTPHOS和Cs 2 CO 3在Ñ，Ñ在80二甲基甲酰胺（DMF）℃下反应1个小时后，将所需产物以高收率形成。该催化体系显示出高的官能团耐受性。

  The development of efficient methods for accessing fluorinated functional groups is desirable. Herein, we report a two-step method that utilizes catalytic copper for the decarboxylative trifluoromethylation of propargyl bromodifluoroacetates is described. This protocol affords a mixture of propargyl trifluoromethanes and trifluoromethyl allenes.
