  Structurally diverse alcohols and phenols were trimethylsilylated in a clean and efficient reaction with hexamethyldisilazane (HMDS) based on the use of a catalytic amount of N-bromosuccinimide under both dichloromethane and solvent-free conditions at room temperature. Deprotection of trimethylsilyl ethers was also be achieved efficiently in the presence of a catalytic amount of NBS in methanol at ambient temperature.Key words: N-bromosuccinimide, solvent-free, alcohols, phenols, hexamethyldisilazane, trimethylsilyl ether, catalyst, detrimethylsilylation.

  Provided are a novel acyclic carbene ligand for ruthenium complex formation; a ruthenium complex catalyst using the ligand; a method of using the complex as a catalyst in an ethylene-metathesis ethenolysis reaction; a method of preparing the ruthenium complex catalyst; and a method of preparing a linear alpha-olefin, the method including the step of reacting a linear or cyclic alkene compound in the presence of the ruthenium complex catalyst. The acyclic carbene ligand of the present invention and the ruthenium complex catalyst using the same have high selectivity and turnover number for terminal olefin formation in an ethylene-metathesis ethenolysis reaction, and thus linear α-olefins may be prepared with a high yield.

  the similarly bulky acyclic diaminocarbenes that show significant distortion from the coplanarity. The Au(I) complexes of AAOCs exhibited high efficiency in the hydroamination of alkenyl ureas. Bulkier AAOC–Au(I) complexes displayed faster reaction rates and higher conversions. The reaction rate, yield, and stereoselectivity observed with the AAOC–Au(I) catalyst were better than those with acyclic diaminocarbene

  通过TMS-Cl消除途径，从氯亚胺盐和烷氧基硅烷中以高收率制备了一系列空间要求高的无环氨基氧化碳烯（AAOC）。通过Au（I）配合物的X射线晶体学研究确定了大体积AAOC的空间分布。埋入体积百分比值（％V BurAAOC配体的）范围从35.8％到47.9％。无环氨基氧卡宾在卡宾中心周围保持共面性，与同样庞大的无环二氨基卡宾显示出明显的共面畸变，这形成了鲜明的对比。AAOCs的Au（I）络合物在烯基脲的加氢胺化反应中显示出高效率。较大的AAOC–Au（I）配合物显示出更快的反应速率和更高的转化率。用AAOC-Au（I）催化剂观察到的反应速率，收率和立体选择性要好于无环二氨基卡宾Au催化剂，并且可与迄今为止报道的最佳结果相媲美。

  The 1:1 and 1:2 reactions of TiCl4 with Me3SiO-2,6-(CH3)2C6H3 produced TiCl3[O-2,6-(CH3)2C6H3]2(THF)2 (1) and TiCL2[O-2,6-(CH3)2C6H3]2(THF)2 (2), respectively, bearing six-coordinated geometry around Ti. The compound 2 assumes the cis-geometry regarding the two phenoxy groups and THF is coordinated in the trans position of the phenoxy groups. Similarly, the 1:1 and 1:2 reactions of NbCl5 with the trimethylsilyl phenyl ether provided NbCl4[O-2,6-(CH3)2C6H3]2(THF) (7) and NbCl3[O-2,6(CH3)2C6H3]2(THF) (8), respectively, with octahedron structure. The THF molecule again locates in the trans position of a phenoxy group in both cases and the two phenoxy groups of 8 locate in the cis position. Tungsten mono-phenoxide, WCl5[O-2,6(CH3)2C6H3]2 (12), also has octahedron structure. In cases of tungsten-bis-phenoxides, WCl4[O-2,6-(CH3)2C6H3]2 (13) and WCl4[O-2,6-(i-C3H7)C6H3]2 (14), the former has trans structure while the latter has cis structure regarding the phenoxy groups. A unique square pyramidal geometry has been observed in the tetrakis(phenoxy) tungsten, WCl[O-2,6-(CH3)2C6H3]4 (16).
