Determination of the lipophilicity of 2'-hydroxychalcones by RP HPLC method [PDF]
Hemijska Industrija, 2016 Lipophilicity of twelve synthesized chalcones, whose ring B is a ortho, meta or para monosubstituted with alkyl, oxyalkyl groups or halogens was determined by reverse phase liquid chromatography, using octadecyl-functionalized (RP-18) silica gel

Synthesis, spectral correlation and insect antifeedant activities of some 2-benzimidazole chalcones
Journal of Saudi Chemical Society, 2016 Some substituted styryl 2-benzimidazole ketones have been synthesised by fly-ash:H2SO4 catalysed aldol condensation of 2-benzimidazole methyl ketone and various substituted benzaldehydes in microwave oven. The yields of these chalcones are more than 70%.

Thermal study of chalcones [PDF]
Journal of Thermal Analysis and Calorimetry, 2018 Chalcones α-β-unsaturated ketones are found in large plant species. Synthesis of chalcones and its three analogues hydroxy group at 2′, 3′ and 4′ positions (2–4) was carried out. The studies of thermal behavior were made by thermogravimetry (TG) and differential scanning calorimetry, both under oxygen and nitrogen purge gases.

Study of Michael addition on chalcones and or chalcone analogues
Journal of Saudi Chemical Society, 2012 AbstractMichael addition reaction of 1,3-diphenyl-propenone 1a, e, and f with o-amino thiophenol in the presence of indium trichloride gave the benzothiazine derivatives 2a–c. Condensation of the compound 1a, e with o-phenylene diamine in triethylamine gave the benzodiazepine derivatives 3a–b.
