The Synthesis of 3-Aryl-6-alkylpyridazines

Liang, Jason

, p. 1297 - 1299 (2007/10/02)

Nine compounds of general structure R-X-Y-R' where X is a para-disubstituted phenyl ring and Y is a 3,6-disubstituted-pyridazine ring were synthesized.These can be used as liquid crystal dopents.A general procedure for their synthesis was developed.N-Alkyl benzene and ethyl butyrylacetate were used as starting materials.The purification of reaction intermediates was not necessary if preparative hplc was used to purify the final products.Very pure materials were obtained with good yield.Their structure was confirmed by carbon 13 nmr.
