“…6 Although many different substrates and conditions have been explored since then, the fundamental working principle is mostly based on adding a carbamoyl radical (•CONR2) to a suitable acceptor. 7 These radicals are long-lived and nucleophilic owing to strong conjugation of the non-bonding electrons of the oxygen with the SOMO. 8 Photocatalytic approaches provide a sustained and controlled radical formation from suitable precursors under milder operating conditions than conventional approaches.…”

“…[34][35][36][37][38][39][40][41] Os protocolos utilizados pela equipe de Elad necessitavam da presença de fotosensitizadores, acetona e benzofenona, que ao serem excitados pela luz ultravioleta, atingem seu estado triplete e abstraem um hidrogênio do grupo formil da formamida. 42 Entre os compostos que reagiram com a carbamoíla de formamida estão ésteres α,β-insaturados, 34 compostos aromáticos, 35 alcenos, 36-38 acetilenos 39,40 e dienos 41 (Esquema 6).…”
