已经开发了可靠的合成氧磺酰叠氮化物的方法,并将其应用于由CuI均匀催化的叠氮化物,炔烃和胺的三组分偶联反应,这导致了N-氧磺酰am的形成,收率很高。为了充分评估对该偶联反应的催化活性,有两个配位框架,即无微孔的Cu 2 I 2(PDIN)和有微孔的Cu 2 I 2(BTTP4)(PDIN = 1,4-亚苯基二异烟酸酯,BTTP4 =苯- 1,3,5-三基三异烟酸)是通过简单的一锅反应制备的非均相催化剂。催化结果表明,无孔Cu 2 I 2(PDIN)对三组分偶联反应几乎没有活性,而微孔Cu 2 I 2(BTTP4)是合成N-氧磺酰基am的有效多相催化剂。此外,相对于炔烃基质,多孔Cu 2 I 2(BTTP4)表现出择形性能,并且芳族炔烃优于脂族炔烃。通过一系列物理技术研究了Cu 2 I 2(BTTP4)框架中催化活性位的位置,包括粉末XRD,CO 2 气体吸附,红外光谱,能量色散X射线分析和

The synthesis and the infrared and massspectra of diaryl and aryl alkyl sulfate diesters are described. The massspectra of these two classes of compounds consistently showed an intense molecular ion and two or three additional intense, diagnostic ions. Their infrared spectra also gave information useful for characterizing and differentiating these two classes of compounds.

Arylimidazolylsulfonates participate as electrophilic coupling partners in palladium-mediated cross-coupling reactions. The arylimidazolylsulfonates display good stability while maintaining good reactivity in a variety of palladium-catalyzed coupling reactions. Imidazolylsulfonates are a practical and economic alternative to triflates.
