Abstract
A number of 2-aryl-2H-chromene-4-carbonitriles were synthesised by cyanation of 2-aryl-3-nitro-2H-chromenes using trimethylsilyl cyanide (TMSCN) in the presence of tetrabutylammonium fluoride (TBAF) in moderate yields via a Michael addition/elimination pathway. The structures of all the products were characterised thoroughly by NMR, IR and HRMS spectroscopy and X-ray crystallographic analysis.
