The review summarises various photo- and electrochemical strategies for trifluoromethylation and fluoroalkylation of different C(sp3)–H, C(sp2)–H, and C(sp)–H bonds in several classes of organic molecules.
An organophotoredox-catalyzed direct Csp3–H alkylation of 3,4-dihydroquinoxalin-2-ones employing N-(acyloxy)phthalimides to provide corresponding products in good yields is described.
In this review, we summarize various strategies for constructing CF2H groups based on different approaches, resulting in a series of difluoromethyl derivatives.
A convenient and efficient copper-catalyzed oxidative C3-cyanoarylation of quinoxalin-2(1H)-ones is developed using 3-aminoindazoles as efficient arylating agents via the cleavage of two C–N bonds.
Recent advances in the photo-promoted C3–H alkylation reaction of quinoxalin-2(1H)-ones with different alkylation agents.
