An efficient procedure for catalyst solubility, recycling and easy product isolation in oxidation of thiols to disulfides with molecular oxygen catalyzed by cobalt(II) phthalocyanines dissolved in ionic liquid at room temperature is reported.

An efficient procedure is described for catalyst recycling and easy product isolation in alkene epoxidation with hydrogen peroxide catalyzed by water-soluble iron(III) porphyrins in environmentally benign and ambient temperature ionic liquids.

Graphite oxide and graphene oxides have been used as solid catalysts for the synthesis of 5,5-dialkyldipyrromethanes and calix[4]pyrroles in organic and aqueous solutions at room temperature.

Efficient and facile reductions of flavones with sodium borohydride (NaBH₄) catalyzed by cobalt(II) phthalocyanines afford cis-flavan-4-ols in 89–97% yields.

Two novel 3,12- and 3,7-bis(4′-nitrophenyl)-azo-5,5,10,10,15,15,20,20-octamethyl calix[4]pyrroles were prepared and studied as potential anion binders for AcO ⁻ and H₂PO₄ ⁻; the isomeric pair not only allowed for the colorimetric detection but also helped to discriminate the geometrically different anions.

An efficient, simple, and rapid synthesis of 14‐alkyl‐or aryl‐14‐H‐dibenzo[a,j]xanthenes is reported by one‐pot condensation of 2‐naphthol with alkyl or aryl aldehydes in the presence of sulfonyl‐functionalized acidic ionic liquids at 125°C.
