[ 1 ] - Metal complexes of unsaturated polycarbonyl compounds derived from benzoyl acetone and aromatic aldehydes

Condensation of aromatic aldehydes with benzoyl acetone under specified conditions yieldedtwo series of polycarbonyl compounds in which the keto group is attached to olefinic linkage.Spectral and analytical data revealed the formation of an unsaturated triketone from pyridine-3-carbaldehyde and unsaturated diketone from furfural, salicylaldehyde and 2-hydroxynaphthaldehyde. Analytical, IR, 1H N...

[ 2 ] - Arylazo derivatives of some fluorinated β-diketones and their metal complexes

Phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. Analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. The monobasicbidentate coordination of the phenylazo derivative...
