Abstract
Number of semicarbazones of 4(4′-n-alkoxybenzoyloxy) benzaldehydes are synthesized. They are cy-clized to respective amino-oxadiazoles. Both the series of compounds exhibit mesomorphism. However, the decomposition is a major problem for semicarbazones. Compounds of both the series are characterized by elemental analysis, UV, IR spectra and NMR spectra.Keywords
