Abstract

Chemistry Chemistry, Organic Physical Sciences Science & Technology
Novel chromeno[2,3-d]pyrimidinyl and bis(chromeno[2,3-d]pyrimidinyl)phosphines and chromeno[2 ',3 ':4,5]pyrimido[2,1-d][1,3,5,2]triazaphosphinine were obtained in a simple one-pot procedure via treatment of 2-imino-2H-chromene-3-carboxamide with phenyl phosphorus isothiocyanates. Possible reaction mechanisms were proposed. The structures of the obtained products were confirmed by elemental analyses and spectral tools.
