  Selenium-mediated conversion of alkynes into .alpha.-dicarbonyl compounds

  摘要：

  The reaction of terminal and internal alkynes with diphenyl diselenide and ammonium peroxydisulfate in methanol proceeds smoothly to give alpha-keto acetals and alpha-keto ketals, respectively. This one-pot procedure is suggested to proceed through the initial formation of phenylselenenyl sulfate, a strong electrophilic reagent which effects the methoxyselenenylation of the alkynes. The addition products thus formed suffer methoxydeselenenylation giving the observed products and regenerating the phenylselenenylating agent. In some cases the reaction can be carried out using only catalytic amounts of diphenyl diselenide. The same reaction carried out in the presence of water or of ethylene glycol gives the unprotected or the diprotected alpha-dicarbonyl compounds, respectively.

• Transition-Metal-Free Alkynylation of Aryl Chlorides
  作者：Thanh Truong、Olafs Daugulis

  DOI：10.1021/ol2014736

  日期：2011.8.19

  Two sets of conditions have been developed for a base-mediated, transition-metal-free alkynylation of aryl chlorides that proceeds via benzyne intermediates. The first set of conditions Involves the use of TMPLI base in a pentane/THF mixture at 25 degrees C. The second set Involves use of a metal alkoxide base in dioxane at elevated temperature. Reasonable functional group tolerance has been observed. Fluoro, trifluoromethyl, silyl, cyano, and alcohol functionalities are compatible with the reaction conditions.

  日期：——

  Phenylethynyl radicals, generated by the photolysis of phenyliodoacetylene, react with aromatic compounds to give substitution products. From the orientation and the relative reactivity data obtained from their reaction with several monosubstituted benzenes it is concluded that the phenylethynyl radical possesses an electrophilic character; partial rate factors for the meta- and para-positions can
