A series of 4-chloro-7-dialkylaminocoumarins has been synthesized by heating m-diethylaminophenol, m-N-piperidinophenol, m-N-morpholinophenol, and 8-hydroxyjulolidine, respectively, with malonic acids in the presence of excess phosphorus oxychloride.The feasibility of preparing other 4-substituted 7-aminocoumarins from these 4-chloro derivatives has been demonstrated using as an example the reactions of 4-chloro-7-diethylaminocoumarins with sodium ethoxide, hydrazine, and dibutylamine.The spectral and luminescence characteristics of these newly synthesized compounds have been investigated.
