An efficient route to benzothiophenes via visible-light induced cyclization of 2-alkynylanilines with disulfides under transition-metal-free and photocatalyst-free conditions was developed.
A green and efficient route for the synthesis of trisubstituted hydroxylamines from β-keto ester, 2-nitrosopyridine and aryldiazoacetates has been reported. This multicomponent reaction occurred under mild conditions without catalysts or additives.
An efficient synthesis of 3-acylindoles via visible-light promoted C3-acylation of free (NH)- and N-substituted indoles with α-oxocarboxylic acids was developed.
A photocatalytic radical di- or trifluoromethylation/cyclization of methacryloyl benzamides with fluorinated sulfones provided an efficient route to CF2H/CF3-containing isoquinoline-1,3(2H,4H)-diones.
Visible-light-mediated trifluoromethylthiolation of N-(o-cyanobiaryl)acrylamides with N-trifluoromethylthiosaccharin as the source of SCF3 radicals provided an efficient route to SCF3-containing ring-fused phenanthridine derivatives.
The use of photocatalysts for visible light mediated reversible deactivation radical polymerization (RDRP) provides an efficient route for the synthesis of well-defined polymers with spatial, temporal and sequence control.
A mild and efficient route to prepare nitriles from aldehydes by combining photoredox catalysis with oxoammonium cations is reported. The methodology is also extended to the one-pot two-step conversion of alcohols to nitriles.
