	The formation of carbon-nitrogen bonds holds paramount importance in the realm of synthetic organic chemistry, finding extensive applications in the synthesis of pharmaceuticals, agrochemicals, and organic materials. Herein, we describe a novel EDA complex mediated, metal- and photocatalyst-free, visible-light-initiated direct C-3 amination of biologically important, quinoxalin-2(1H)-one moiety. The key to the success lies in the formation of a photoactivated electron donor-acceptor complex between quinoxalin-2(1H)-one and amine, which undergo subsequent electron transfer reaction to effect the desired transformation. A diverse array of 3-aminoquinoxalin-2(1H)-ones were prepared employing this process and the yields are up to 87\%. This work represents a significant advancement toward a more environmentally friendly and efficient approach, characterized by mild reaction conditions and a high atom economy.</p>

	A simple and efficient strategy for the synthesis of structurally diverse beta,beta-diarylmethine substituted isoxazoline derivatives have been developed. This approach employs a manganese-promoted oxidative cyclization coupled with a 1,6-conjugate addition of unsaturated oximes to p-quinone methides. The key features of this study include the formation of C-O and C-C bonds through intramolecular and intermolecular interactions, facilitated by in situ generated iminoxyl radicals. beta,beta-diarylmethine substituted isoxazolines, bearing a wide range of functional groups, were isolated in high yields.</p>
