Usage

General Description

4,5-Diphenylimidazolin-2-one, also known as DPI, is a chemical compound with the molecular formula C15H12N2O. This white crystalline solid is a heterocyclic compound that is commonly used as a photoinitiator in the formulation of photocurable materials, such as inks, coatings, and adhesives. It works by absorbing ultraviolet light and initiating a chemical reaction that leads to the curing or hardening of the material. DPI is known for its high reactivity and efficiency in initiating polymerization, making it a key ingredient in UV-curable systems. It is also used in the production of dental materials, optical lenses, and electronic devices. Additionally, DPI has potential applications in the field of photodynamic therapy and as a pharmaceutical intermediate for synthesis of other compounds.

Efficient Green Synthesis and Computational Chemical Study of Some Interesting Heterocyclic Derivatives as Insecticidal Agents

A series of 5,5-diarylhydantoin (Dilantin) 3, 4, and 7, imidazole 1, 2, 5, 6, 8, and 9, thiazole 10–12, triazinthione 13, 15, 16, and 17, and thiadiazine 14 derivatives, containing diverse hydrophobic groups, were green synthesized through one-pot stepwise reaction of aromatic aldehydes, vitamin B1, and nitrogen nucleophiles, for example, urea, thiourea, and thiosemicarbazide using grinding technique as well as conventional thermal methods. Such synthesized compounds have potent insecticidal activities; for example, compounds 4, 6, and 17 exhibited the highest insecticidal activity against both Plutella xylostella and Helicoverpa armigera with minimum inhibitory concentration values at 500?μg/mL and LD50 activities at 50?μg/mL. The density functional theory was then applied to explore the structural and electronic characteristics of these compounds. All the synthesized compounds have been characterized based on their elemental analyses and spectral data.
