A series of monofunctionalized 1,3,5,7-tetraarylazaBODIPYs containing functional groups such as p-hydroxymethyl phenyl, p-hydroxyphenyl, p-cyanophenyl, p-nitrophenyl, and p-formylphenyl groups at the 1-position of the azaBODIPY core were synthesized by mi

, (2020)
Ca(OTf)2 in combination with NBu4.BF4 was established to function as an efficient catalyst system for one-pot Claisen-Schmidt condensation under neat conditions. Substituted acetophenones and benzaldehydes were coupled in situ to afford their corresponding chalcones in excellent yields. The method, with a broad range of substrate tolerance and mild operational conditions can produce assorted chalcone derivatives in moderate to high yields from easily accessible starting materials.
Iron(III) phthalocyanine chloride-catalyzed oxidation-aromatization of α,β-unsaturated ketones with hydrazine hydrate: Synthesis of 3,5-disubstituted 1H-pyrazoles

We have developed an iron(III) phthalocyanine chloride-catalyzed oxidation-aromatization of α,β-unsaturated ketones with hydrazine hydrate. Various 3,5-disubstituted 1H-pyrazoles were obtained in good to excellent yields. This method offers several advantages, including room-temperature conditions, short reaction time, high yields, simple work-up procedure, and use of air as an oxidant. The catalyst can be recovered and reused five times without loss of activity.
