A functionalized phosphine ligand with a pentaarylbenzene moiety in palladium-catalyzed Suzuki–Miyaura coupling of aryl chlorides
摘要:
A functionalized phosphine with a pentaarylbenzene moiety was found to facilitate the palladium-catalyzed Suzuki-Miyaura coupling of aryl chlorides. The new ligand achieved high turnover numbers (up to TON 5000). (C) 2008 Elsevier Ltd. All rights reserved.
Straightforward access to functionalized pentaarylbenzene derivatives through a quick lithiation
摘要:
A straightforward route to functionalized pentaarylberizene derivatives is described, involving the effective lithiation method of 1-iodo-2,3,4,5,6-pentaarylbenzene. The activated pentaarylbenzene is a potential synton for producing organic materials. (C) 2008 Elsevier Ltd. All rights reserved.
