An electronic structural study of the complete valence shell of [1.1.1]propellane is reported. Binding energy spectra were measured in the energy regime of 3.5-46.5 eV over a range of different target electron momenta, so that momentum distributions (MDs) could be determined for each ion state. Each experimental electron momentum distribution is compared with those calculated in the plane wave ...

Regioselective construction of 4,8,9-trioxygenated 2,3-dihydrobenz[f]indenones, key intermediates for the synthesis of kinamycin antibiotics, was achieved via Diels-Alder reactions (DAR) using 4,7-dioxygenated indanone-type compounds as dienophiles. Reaction of indanetrione with 1-methoxybutadiene gave a 1 : 1 mixture of undesired 4,5,9-trioxygenated 2,3-dihydrobenz[f]indenone and [4.4.3]propel...

Photochemistry. In their Communication (e202303435), Tsuyoshi Mita et al. report a method for the diphosphination of [1.1.1]propellane using visible light.

Sulfonylated aromatics are commonplace motifs in drugs and agrochemicals. However, methods for the direct synthesis of sulfonylated non-classical arene bioisosteres, which could improve physicochemical properties drug agrochemical candidates, limited. Here we report a solution to this challenge: one-pot halosulfonylation [1.1.1]propellane, [3.1.1]propellane bicyclo[1.1.0]butanes that proceeds u...

To achieve a kilojoules-per-mole level of accuracy consistently in computational thermochemistry, the inclusion of post-CCSD(T) correlation effects cannot be avoided. Such effects are included in the W4 and HEAT computational thermochemistry protocols. The principal bottleneck in carrying out such calculations for larger systems is the evaluation of the T(3)-(T) term. We propose a cost-effectiv...

The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H⋯O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C⋯O...

Body centered structures are used as seeds for a variety of structures of rank 3 and higher. Propellane based structures are introduced and their design and topological properties are detailed.
