We report an ultra-fast solvent- and metal-free method for constructing symmetric and unsymmetric disulfides by direct coupling of thiols.
The photochemical direct esterification of aldehydes with alcohols via in situ-generated acyl-bromides under irradiation from purple LEDs was achieved.
The advances in the Povarov reactions under visible-light conditions are highlighted, offering helpful guidance for selecting suitable synthetic protocols.
In this review, 8-aminoquinoline, 8-hydroxyquinoline, and 1-naphthylamine scaffolds are classified, and the constructions of their selective C–H activation systems are reviewed in terms of photocatalytic and electrocatalytic synthesis.
A photocatalyst-free, simple and green method for visible light driven photocatalytic synthesis of gem-dihaloenones from alkynes, tetrahalomethanes and water has been developed.
