Abstract Here we report our investigation of 1‐bromo‐3,5,7‐triphenyladamantane ( 1 ) and the elucidation polymorphic crystals A B using single crystal X‐ray diffraction. In monoclinic system P 2 / n ), observed CH–π interactions, while Br⋅⋅⋅Br interactions are absent. Conversely, an apparent factor in formation R ). We compare findings with 1,3,5,7‐tetraphenyladamantane characterized by numerous solid. Computational analyses were employed to investigate within characteristic dimers present unit cells , including visualization noncovalent use atoms‐in‐molecules approach as well MO analyses. These support notion London dispersion (LD) dimer‐dimer between phenyl moieties, whereas exhibits additional contacts. contrast, exclusively held together stacking LD a feature absent polymorphs . Both forms emit white light when subjected 900 nm continuous wave laser irradiation, displaying subtle blue shift compared The absence causes small red‐shift emission spectrum.

The incorporation of oxygen atoms from air under aerobic conditions plays an important role in organic synthesis. Herein, Brønsted acids are found to be a two-in-one strategic catalyst transform enamines β-oxoamides and amines pyrrolin-4-ones without external photocatalyst visible-light conditions. acid can inhibit the C-C bond fragmentation [2 + 2] adduct enamine
