如题！！！！！！！ 欢迎大家多多发言 叫更多人来关注这个金属吧！ 就是Palladium ........ 我抛砖引玉...........  推荐关于Pd催化的专著一本 Palladium Reagents and Catalysts : New Perspectives for the 21st Century ISBN: 0470850329 Title: Palladium Reagents and Catalysts : New Perspectives for the 21st Century Author: Jiro Tsuji Publisher: John Wiley & Sons http://muchong.com/bbs/viewthread.php?tid=243678&fpage=1  为免网络侵权纠纷和给小木虫带来不必要的麻烦，,本人只转帖国外论坛发布的下载地址,请理解!!本人没有上传这本书,!!这书只供个人学习,研究或者欣赏他人发表的作品!!

这是美国耶鲁大学John F. Hartwig教授（我的偶像之一）的一篇近作！ Palladium-Catalyzed Intermolecular -Arylation of Zinc Amide Enolates under Mild Conditions  Takuo Hama, Darcy A. Culkin, and John F. Hartwig;J. Am. Chem. Soc.; 2006; 128;128(15) pp 4976 - 4985; (Article) DOI: 10.1021/ja056076i. Abstract: The intermolecular -arylation and vinylation of amides by palladium-catalyzed coupling of aryl bromides and vinyl bromides with zinc enolates of amides is reported. Reactions of three different types of zinc enolates have been developed. The reactions of aryl halides occur in high yields with isolated Reformatsky reagents generated from -bromo amides, with Reformatsky reagents generated in situ from -bromo amides, and with zinc enolates generated by quenching lithium enolates of amides with zinc chloride. This use of zinc enolates, instead of alkali metal enolates, greatly expands the scope of amide arylation. The reactions occur at room temperature or 70 C with bromoarenes containing cyano, nitro, ester, keto, fluoro, hydroxyl, or amino functionality and with bromopyridines. Moreover, the reaction has been developed with morpholine amides, the products of which are precursors to ketones and aldehydes. The arylation of zinc enolates of amides was conducted with catalysts bearing the hindered pentaphenylferrocenyl di-tert-butylphosphine (Q-phos) or the highly reactive, dimeric, Pd(I) complex {[P(t-Bu)3]PdBr}2. |

这是发表在JACS上另外关于Pd催化的近作！ Room Temperature Palladium-Catalyzed Intramolecular Hydroamination of Unactivated Alkenes  Forrest E. Michael* and Brian M. Cochran;J. Am. Chem. Soc.; 2006; 128; pp 4246 - 4247. Abstract: A mild and facile Pd-catalyzed intramolecular hydroamination of unactivated alkenes is described. This reaction takes place at room temperature and is tolerant of synthetically useful acid-sensitive functional groups. The formation of hydroamination products rather than oxidative amination products is due to the use of a tridentate ligand on Pd which effectively inhibits -hydride elimination. |

这是一篇用微波炉做的反应，我直觉应该上JACS！ Microwave-Promoted Aminocarbonylation of Aryl Iodides, Aryl Bromides, and Aryl Chlorides in Water  Xiongyu Wu, Jenny K. Ekegren, and Mats Larhed; Organometallics; 2006; 25; pp 1434-1439.. Abstract: Fast and direct methods have been developed for the small-scale carbonylative preparation of benzamides from aryl iodides, bromides, and chlorides in pure water. The reactions proceed by palladium catalysis using noninert conditions, solid Mo(CO)6 as the CO source, and controlled microwave superheating. Within 15 min of microwave processing, more than 90 aminocarbonylations were successfully performed in useful to excellent yields employing both primary and secondary amines. Using appropriate ratios of starting amines and aryl halides, the competing hydroxycarbonylation reaction was suppressed and only trace amounts of the corresponding carboxylic acids were detected. Based on this aqueous carbonylation, a facile preparation of a novel HIV-1 protease inhibitor was achieved. |
