Novel photo-induced coupling reaction of 9-fluorenylidenemalononitrile with 10-methyl-9,10-dihydroacridine
Abstract
9-Fluorenylidenemalononitrile reacts with 10-methyl-9,10-dihydroacridine in deaerated acetonitrile under irradiation with λ > 320 nm to give a coupling product 9-dicyanomethyl-9-(10′-methyl-9′-acridinyl)fluorene, characterized by X-ray crystallographic, MS and NMR analyses.
