  日期：2014.9.8

  A one‐pot protocol for the synthesis of N‐aryl 1,2,3‐triazoles from arenes by an iridium‐catalyzed CH borylation/copper catalyzed azidation/click sequence is described. 1 mol % of Cu(OTf)2 was found to efficiently catalyze both the azidation and the click reaction. The applicability of this method is demonstrated by the late‐stage chemoselective installation of 1,2,3‐triazole moiety into unactivated

  copper(II) bromide or chloride converts arylboronic esters to the corresponding aryl halides. A variety of arenes containing alkoxy, alkyl, halogen, nitrile, ester, amide, and pivaloyl and TIPS-protected alcohols were converted to the corresponding 3,5-disubstituted aryl bromides and chlorides in yields ranging from 46% to 85%. In addition, 2,6-disubstituted and 3-substituted pyridines were converted

  One-step conversions of 1,3-disubstituted benzenes to aryl boronates and 2,6-disubstituted pyridines to heteroaryl boronates are described. Microwave heating was used for all reactions. [(COD)Ir(μ-OMe)]2 and 4,4′-di-tert-butyl-2,2′-bipyridine were used as catalysts, in methyl tert-butyl ether. Acceleration of the rate of reaction was remarkable compared with that of same reaction under conventional heating conditions.

  A mild one-pot protocol for the synthesis of symmetrical biaryls by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes is described. The regiochemistry of the biaryl formed is sterically controlled as dictated by the C-H borylation step. The methodology is also successfully extended to heteroarenes. Some of the products obtained by this approach are impossible to obtain

  one‐pot method for the site‐selective alkylation of arenes controlled by steric effects is reported. The process occurs through Ir‐catalyzed CH borylation, followed by Pd‐ or Ni‐catalyzed coupling with alkyl electrophiles. This selectivity complements that of the typical Friedel–Crafts alkylation; meta‐selective alkylation of a broad range of arenes with various electronic properties and functional
