Emerging Trends in Organic Photoreactions Utilizing Disulfides

European Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, EarlyView.
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
