light-emitting diodes, PPh3 catalyzes the iododecarboxylation of aliphatic carboxylic acid derived N-(acyloxy)phthalimide with lithiumiodide as an iodine source. The reaction delivers primary, secondary, and bridgehead tertiary alkyl iodides in acetone solvent, and the alkyl iodide products were easily used to generate C–N, C–O, C–F, and C–S bonds to allow various decarboxylative transformations without

Herein, a metal-free photocatalyzed site- and regioselective C−H alkylation of electron-rich arenes at room temperature using alkenes as the alkylating reagents is described for the first time. The alkylation proceeds in the absence of any directing groups, and tolerates both activated and unactivated alkenes to deliver alkylated arenes with broad functional-group tolerance, providing an alternative
