cross coupling. The N-aryl substituted complex 3b was a highly efficient precatalyst and successfully employed in Suzuki-Miyaura cross coupling reactions of (hetero)aryl chlorides with arylboronic acids in air. In addition, the oxidativeaddition step of the reaction mechanism involving chlorobenzene and the catalysts 3a, 3b, 3c and 3d were computationally investigated by the DFT-ω-B97X-D method and
制备了一系列的N-芳基(2a,b)或苄基(2c,d)取代的哌啶并咪唑啉盐及其钯配合物(3a - d),并通过1 H,13 C NMR,IR光谱和元素分析进行了表征。3a和3c的晶体结构已经通过X射线晶体学确定。热重分析(TGA)用于复合物(3a – d)。钯配合物已被用作铃木-宫浦交叉偶联的催化剂。N-芳基取代的配合物3b是一种高效的预催化剂,已成功用于空气中(杂)芳基氯与芳基硼酸的Suzuki-Miyaura交叉偶联反应。此外,通过DFT-计算方法研究了涉及氯苯与催化剂3a,3b,3c和3d的反应机理的氧化加成步骤。ω-B97X-D法与催化结果完全吻合。为了测量新配体的σ-给体和π-受体性质,还制备了羰基铑配合物。

ABSTRACT A simple and efficient catalytic system for PdCl2 catalyzing the Suzuki–Miyaurareaction of dibromobenzene and arylboronic acid has been developed by using 3-(diphenylphosphino)propanoic acid as a ligand in dimethylsulfoxide at 100 °C. Using this method, a series of symmetrical terphenylderivatives were obtained with remarkably good yields, up to 93%. GRAPHICAL ABSTRACT

Synthesis of selectively metallated diporphyrins with electron-accepting moieties is described. Steady-state fluorescence spectra of these compounds snowed substantial quenching of the fluorescence of the free-base porphyrin. A possible “superexchange” mechanism of long-range electron transfer is discussed.
We synthesized the novel seco cyclopropa[c]pyrrolo[3,2-e]indole (CPI) bisalkylators and evaluated their antitumor activity. Among these derivatives, 11a (AT-760), in which the two seco 3-methoxycarbonyl-2-trifluoromethyl CPI (MCTFCPI) moieties are connected with a 3,3'-(1,4-phenylene)bisacryloyl group, was found to exhibit more potent cytotoxicity and antitumor activity against HeLaS3 human uterine
