Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

A Green and Highly Selective Approach to Copper‐Catalyzed Transfer Hydrodeuteration of Alkenes and Alkynes Using D2O

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Highly selective deuteration is now possible with a green and more environmentally benign reaction protocol for Cu‐catalyzed transfer hydrodeuteration of alkenes and alkynes. This was applied to the synthesis of precisely deuterated alkanes, including deuterated complex molecules and high enantiopurity isotopomers. Precisely labeled small molecules are
