Abstract

Abstract : New fluorescent compounds, 2‐substituted indeno[1, 2‐ d ]pyrimidin‐5‐ones (3a, 3b, 3c, 3d ) were synthesized in good yield by the reaction of 2‐[bis(methylsulfanyl)methylene]indan‐1, 3‐dione (1 ) with the respective amidine derivatives [guanidine carbonate (2a ), acetamidine hydrochloride (2b ), S ‐methylisothiourea sulfate (2c ), and S ‐benzylisothiourea sulfate (2d )]. 4‐Substituted amino‐2‐aminoindeno[1, 2‐ d ]pyrimidin‐5‐ones (7b, 7c, 7d ) were synthesized by aone‐pot reaction of1, 2a and the respective amine compounds (4b, 4c, 4d ) in pyridine. These fused pyrimidine derivatives showed fluorescence in the solid state. Abstract :
