[2.2]Paracyclophane (PCP) derivatives have been promising platforms to study the element of planar chirality and through-space electronic communications in π-stacked molecular systems. To access enantiomerically pure derivatives thereof, a kinetic resolut

The first examples of through-space conjugated thermally activated delayed fluorescence (TADF) emitters based on a [2.2]paracyclophane (PCP) skeleton with stacked (coplanar) donor-acceptor groups have been synthesized. The optoelectronic properties are studied by the relative configuration, cis (pseudo-geminal) and trans (pseudo-para), of the donor and acceptor groups.

The palladium-catalyzed direct C-H bond acetoxylation of [2.2]paracyclophanes has been investigated. Various mono- and disubstituted [2.2]paracyclophanes were subjected to typical Sanford acetoxylation conditions. Oxime ethers, an oxime acetate, a pyridine, and a pyrazole with [2.2]paracyclophane cores underwent direct ortho-acetoxylation in good to excellent yields using 1-5 mol% of palladium(II) acetate in combination with iodobenzene diacetate as oxidant. The reactions could be performed on a multigram scale, and the ortho-acetoxylated [2.2]paracyclophanes were suitable for further functionalizations affording a hydroxy[2.2]paracyclophane derivative and a planar chiral benzoxazole.
