By means of the Vilsmeier reaction, starting with various 4-substituted 7-dialkylaminocoumarins having an open position 3, the corresponding 3-formyl derivatives have been obtained, and their spectral and luminescence characteristics have been studied.The 13C NMR spectra and acid-base properties of a number of the synthesized compounds have been examined.

A series of 4,7-diamino-3-formylcoumarins has been synthesized by the reaction of 7-dialkylamino-4-chloro-3-formylcoumarins with primary and secondary amines and by the formylation of 4,7-diaminocoumarins by the Vilsmeier reaction. The corresponding Schif
