new series of long-lived singlet diradicals, viz., 1,2-diazacyclopentane-3,5-diyl, were identified, and their electronic structures and novelreactivities were thoroughly studied using laser-flash photolysis (LFP), product analysis, and computational studies. A direct observation of the thermal equilibration (fast process) between the singlet diradicals and the corresponding ring-closing compounds was

We report an environmentally benign protocol for the C–H alkoxycarbonylation of arenes with alkylcarbazates directed by N‐heterocyclic substituents. Pd(OAc)2 is used to catalyze this oxidative free radical carbonylative transformation. The reaction is tolerant to a wide variety of functional groups to give the products in good yields and excellent regioselectivity.
