Abstract
An up-to-date short review of the chalcone methodologies is presented, which is the most
interesting and beneficial for choosing the desired protocol to synthesize suitable derivatives of chalcones.
Chalcones are fluorescent, stable compounds which contribute to the synthesis of various
pharmacologically important heterocyclic structure-based derivatives. Chalcone has displayed a remarkable
curative efficiency to cure several diseases. Several schemes and methodologies have been
reported for employing different catalysts and reagents. The development of improved methodologies
of α, β-unsaturated carbonyl compounds is still on going. In this review, synthetic methodologies
and their recent modification in designing new methods with efficient, economical, eco-friendly
and high yield are discussed.

Abstract
The debromination of vicinal dibromo compounds to generate alkenes usually requires harsh reaction conditions and the addition of catalysts. Just recently the visible-light-induced debromination of vicinal dibromo compounds emerged as a possible alternative to commonly used methods, but the substrate scope of this reaction is limited and a photocatalyst is necessary for the successful conversion of the starting compounds. A catalyst-free visible-light-induced debromination of vicinal dibromo compounds with a base-activated Hantzsch ester as photosensitizer is reported. The method has a wide substrate scope and a broad functional-group compatibility.
