CAS Number 1846598-27-3
4DPAIPN is a typical donor–acceptor fluorophore with excellent redox window and good chemical stability. With four diphenylamine as electron donor groups and two nitrile groups at meta-positions as electron acceptor on a fully substituted benzene ring, 4DPAIPN is very similar in chemical structure to 4CzIPN. The only difference between them is that 4DPAIPN has four diphenylamine groups while 4CzIPN has four carbazole functional groups.
4DPAIPN has emerged as a powerful and effective metal-free organic photocatalyst in a great variety of chemical reactions. 4-alkyl-1,4-dihydropyridines (DHPs) undergo phosphonylation with 9-fluorenyl o-phenylene phosphite under blue LEDs in the presence of 1 mol% 1,2,3,5-4DPAIPN and 200 mol% triethylamine. This reaction is applicable to primary, secondary, and even tertiary DHPs and exhibits a broad substrate scope and excellent functional group tolerance.
