Suzuki-Miyaura cross-coupling reaction, and high catalytic activities of aryl bromides and chlorides are achieved in neatwater. The mercury drop test, poison experiments, and TEM analysis are used to demonstrate the formation of palladiumnanoparticles (NPs) after the catalytic reaction. The effects of pendantionicgroups in L1-L3 on the catalytic activities and structures of the palladium NPs are disclosed

supramolecular catalysts for Suzuki-Miyauracoupling were prepared and characterized by NMR, FT-IR, TEM, XRD, TGA, and XPS. The resulting picolinamide-modified β-cyclodextrin/Pd(II) complex (Pd(II)@PCA-β-CD) showed very efficient catalytic activity for Suzuki-Miyauracoupling of aryl, benzyl, and allyl halides with arylboronic acids in an environmentally benign aqueous solution. Various organic halides

The use of two silicon carbide plates is reported for the preparation of three libraries of organic molecules using microwave heating. In addition, a preliminary study has been carried out, showing that one of the plates can also be used in a proteomics setting. Both the 24-position and 48-position plates heated evenly when irradiated with microwave energy. The 48-position plate was used to prepare a library of N-aryl functionalized β-amino esters via an aza-Michael reaction between anilines and Michael acceptors. The 24-position plate was used to prepare a library of biaryls via a Suzuki coupling methodology and a library of 1,4-dihydropyridines via a Hantzsch synthesis. The 48-position plate was also used to perform the proteolytic digestion of insulin chain B by trypsin.

has been developed for efficient cross-coupling of 3-dimethylaminopropyl diarylborinates with arylchlorides and mesylates. A small amount of water has been found to be crucial in achieving high efficiency in the system. The nickel catalyst system displayed remarkably higher activities to arylchlorides and mesylates than the corresponding tosylates in cross-coupling with not only diarylborinates but
一种实用的镍催化剂体系,由容易获得的反式-NiCl(Ph)(PPh 3)2 / [Iprmim] I / K 3 PO 4 ·3H 2组成。已经开发出甲苯中的O,以使3-二甲基氨基丙基二芳基硼酸酯与芳基氯化物和甲磺酸酯有效地交叉偶联。已经发现少量的水对于实现系统的高效率至关重要。如对照实验所示,在不仅与二芳基硼酸酯而且二芳基硼酸,芳基硼酸,酸酐和三氟硼酸酯交叉偶联中,镍催化剂体系对芳基氯化物和甲磺酸酯的活性比相应的甲苯磺酸酯显着更高。通过使用3–5%mol%的镍催化剂,可以以优异的收率获得各种电子形式的联芳基,而位阻受阻的联芳基的收率则相对较低。
