The first mercury-catalyzed synthesis of 1,2-diketones by alkyne oxidation has been developed. This inexpensive method extends the potential mercury catalysis and allows rapid construction various α-carbonyl amides in good yields with high functional group tolerance.

A new series of oxovanadium (IV) tetraazamacrocyclic complexes type [VO(mac)]SO4, have been synthesized via in situ reaction 1,8-diaminonaphthalene and substituted β-diketones (1-phenyl-3-(phenyl/4-chlorophenyl/4-hydroxyphenyl/4- methoxyphenyl/4-nitrophenyl)-diketone) the presence oxovanadium(IV) sulphate methanol. Attempts to synthesize corresponding metal free macrocyclic ligands did not prov...

The selective synthesis of different products from the same starting materials in water, which is the most abundant solvent in nature, is a crucial issue as it maximizes the utilization of materials. Realizing such reactions for ketones is of considerable importance because numerous organic functionalities can be obtained via nucleophilic addition reactions. Herein, we report chemoselective red...

Using a simple and accessible Teflon AF-2400 based tube-in-tube reactor, a series of pyrroles were synthesised in flow using the Paal-Knorr reaction of 1,4-diketones with gaseous ammonia. An inline flow titration technique allowed measurement of the ammonia concentration and its relationship to residence time and temperature.

Novel organic photoCORMs based on micelle-encapsulated unsaturated cyclic α-diketones were designed and synthesized. These photoCORMs can be activated by visible light, have potentially low toxicity, allow the delivery of carbon monoxide to be monitored by fluorescence imaging techniques, and thus are useful tools for the study of the biological function of CO.
