Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. Application In Synthesis of 1,5-Diphenylpenta-1,4-dien-3-one,
Chalkone dibromides (Ia-c) undergo debromination when treated with sodium hydrogen selenide in boiling ethanol to give chalkones (IIa-c).Likewise dibenzalacetone dibromides (IIIa-c) suffer debromination to give dibenzalacetones (IVa-c) which further interact with sodium hydrogen selenide to give 2,4-diaryltetrahydroselenopyran-4-ones (Va-c).
