Visible light promoted thiol-ene reactions using titanium dioxide.
The radical addition of thiols to alkenes is reported under photoredox conditions, using visible light and TiO2 as a cheap and readily available photocatalyst.
متن کاملVisible light promoted hydration of alkynes catalyzed by rhodium(III) porphyrins.
Visible light promoted hydration of a wide scope of alkynes to ketones catalyzed by rhodium(III) porphyrin complexes was described. The key intermediate β-carbonyl alkyl was observed and independently synthesized. The rate of photolysis is over two orders of magnitude faster than that of the thermal process.
متن کاملVisible Light Promoted Allylic C–H Oxidation
A mild and efficient one-pot visible light-induced method has been developed for the allylic oxidation. The oxidation of allylic systems has played a prominent role in this context as possibly the most widely applied C–H functionalization, owing to the utility of enones. The allylic C–H oxidation is relatively simple and predictable, even on a preparative scale, because active species generated...
متن کاملA Conjugated Microporous Polymer for Palladium‐Free, Visible Light‐Promoted Photocatalytic Stille‐Type Coupling Reactions
The Stille coupling reaction is a versatile method to mainly form aromatic C-C bonds. However, up to now, the use of palladium catalysts is necessary. Here, a palladium-free and photocatalytic Stille-type coupling reaction of aryl iodides and aryl stannanes catalyzing a conjugated microporous polymer-based phototcatalyst under visible light irradiation at room temperature is reported. The novel...
متن کاملHighly efficient synthesis of tetrahydrobenzo[b]pyrans under visible light promoted by cesium carbonate
Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...
