to form thiazol-2-yl-triphenylphosphonium salts, and these phosphoniumsalts react with a wide range of O- and N-centered nucleophiles to give the corresponding ethers, amines, and C-N biaryls. The reactions proceed under mild conditions and allow for the recovery of triphenylphosphine at the end of the sequence. In the presence of hydroxide, phosphoniumsalts undergo disproportionation, resulting in
苯并噻唑与三苯基膦进行区域选择性 C2-H 官能化形成噻唑-2-基-三苯基鏻盐,这些鏻盐与多种 O 和 N 中心亲核试剂反应生成相应的醚、胺和 CN 联芳基。反应在温和条件下进行,并允许在序列末端回收三苯膦。在氢氧化物存在下,鏻盐发生歧化反应,导致苯并噻唑还原,这可用于苯并噻唑的特定 C2 氘化。

A POCl3-mediated, direct amination reaction of heterocyclicamides/ureas with NH-heterocycles or N-substituted anilines is described. Compared to the existing methods, this operationally simple protocol provides unique reactivity and functional group compatibility because of the metal-free, acidic reaction conditions. The yields are generally excellent.

and homoleptic [Ru(L–L′)3]2+ complexes, where bipy = 2,2′-bipyridine and L–L′ is one of nine newpyrazole-containingbidentateligands, have been prepared. Full assignments have been made for the 1H and 13C n.m.r. spectra of the complexes in CD3CN and the origins of the co-ordination-induced shifts are discussed. The absorption spectra and redox properties of the complexes are also discussed.
