their robust structure, well-defined periodic reaction centers, and high porosity. We report Cu3(BTC)2·(H2O)3 (HKUST-1) as an efficient heterogeneous catalyst for aziridination of alkene and ring-opening reaction of activated aziridines. Furthermore, we demonstrate that the transfer of a nitrogen group from PhINTs to olefins and its analogue to give aziridines takes place at the coordinatively unsaturated
金属有机骨架(MOF)由于其坚固的结构、明确的周期性反应中心和高孔隙率而被广泛用于催化。我们报道了Cu 3 (BTC) 2 ·(H 2 O) 3 (HKUST-1) 作为烯烃氮丙啶化和活化氮丙啶开环反应的有效多相催化剂。此外,我们证明了氮基团从 PhINTs 转移到烯烃及其类似物以产生氮丙啶发生在 Cu 3 (BTC) 2的配位不饱和 Cu(II) 位点-MOF; 然而,活化的氮丙啶的开环受 Cu(II) 路易斯酸位点控制,并且通过 MOF 的热活化产生配位不饱和度并不重要。这种催化方法的主要优点是直接形成 C-C、C-N、C-O 和 C-S 键,通过烯烃在一个锅中的同时氮丙啶化开环反应产生 β-芳基磺酰胺衍生物,使用单一催化剂。
