into valuable azabicyclic scaffolds based on the concept of inverse hydride shuttle catalysis. The ternary complexes are readily constructed in situ from three simple precursors and enable a highly modular installation of various substitution patterns. Upon subjection to a unique dual-catalytic system, the transient intermediates undergo an unusual hydride shuttle process that is initiated by a hydride
A series of enamines were photocatalytically cleaved to produce amide products under simple visible-light irradiation from a 45 W household light bulb. Mechanistically, the reactions appear to involve photosensitized formation of a singletoxygenintermediate and a subsequent [2+2] cycloaddition event.
在 45 W 家用灯泡的简单可见光照射下,一系列烯胺被光催化裂解以产生酰胺产物。从机制上讲,这些反应似乎涉及单线态氧中间体的光敏形成和随后的 [2+2] 环加成事件。
