DPPH‐based Antioxidant Screening and Cellulase‐assisted Hydrodistillation of Matourea azurea: Improved Essential Oil Yield and Density Functional Theory Insights Into a Rare Terpene

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Essential oils are rich in bioactive molecules like terpenes and phenolic compounds, but have low yields, making process efficiency crucial. Enzyme‐assisted hydrodistillation is a sustainable alternative, enhancing oil release by degrading the cell wall.

Copper‐Catalyzed Defluorinative Allylboration of Allenes with Trifluoromethyl Alkenes

open access: yesChemistryEurope, EarlyView.
A copper‐catalyzed borylative coupling of allenes with 1‐trifluoromethyl alkenes is reported. The reaction selectively provides synthetically versatile borylated 1,1‐difluoro‐1,5‐dienes that can be converted into a range of medicinally relevant fluorinated compounds. Mechanistic studies reveal a key role of the catalytically generated LiCl by assisting
