  Ruthenium-Catalyzed Carbonylative C–H Cyclization of 2-Arylphenols: A Novel Synthetic Route to 6H-Dibenzo[b,d]pyran-6-ones

  摘要：

  Catalytic carbonylative C-H cyclization of 2-arylphenols can be achieved in the presence of a ruthenium-based catalytic system. The process proceeds efficiently under balloon pressure of CO and produces variously substituted 6H-dibenzo[b,d]pyran-6-one compounds, typically in good to high yields. Functional groups such as the alkoxycarbonyl and acetyl groups as well as halogen atoms (F, Cl, and Br) are well tolerated during the reaction.

  Directed Ortho Borylation of Phenol Derivatives Catalyzed by a Silica-Supported Iridium Complex

  摘要：

  The directed ortho borylation of phenol derivatives protected with an N,N-diethylcarbamoyl group was efficiently catalyzed by an immobilized monophosphine-Ir system, which was prepared in situ from [Ir(OMe)(cod)](2) and a silica-supported, compact phosphine. The utility of the carbamoyloxy group as a leaving group for metal-catalyzed cross-coupling reactions was demonstrated by its utilization in the synthesis of a terphenyl derivative.

• Synthesis of Substituted Monohalobenzenes via Ortho-Selective Cross-Coupling of Dihalobenzenes with Electron-Donating Ortho-Directing Groups
  作者：Kei Manabe、Shunpei Ishikawa

  日期：2008.10

  Dihalobenzenes that possess directing groups such as OH, CH 2 OH, NH 2 , NHAc, or NHBoc were subjected to ortho-selective cross-coupling with Grignard reagents in the presence of palladium-based catalysts to give the corresponding substituted monohalobenzenes. For the dibromo- and dichlorophenols and anilines, hydroxylated terphenylphosphines 1 and 2 were found to be effective ligands for palladium

  在钯基催化剂存在下，将具有导向基团如 OH、CH 2 OH、NH 2 、NHAc 或 NHBoc 的二卤代苯与格氏试剂进行邻位选择性交叉偶联，得到相应的取代单卤代苯。对于二溴和二氯苯酚和苯胺，羟基化三联苯膦 1 和 2 被发现是钯的有效配体，而三环己基膦对于二氯苯甲醇、二氯苯胺和二氟苯来说是优选的。
• Highly Ortho-Selective Cross-Coupling of Dichlorobenzene Derivatives with Grignard Reagents

  DOI：10.1021/ol702646s

  日期：2007.12.1

  Highly ortho-selective cross-coupling of dichlorobenzene derivatives with Grignard reagents was realized using a combination of Pd-2(dba)(3) and PCy3. Use of hydroxylated terphenylphosphines further improved the reactions of dichlorophenol and dichloroaniline.
