Effect of benzocyclobutadieno-annelation on cyclic conjugation in perylene
Macedonian Journal of Chemistry and Chemical Engineering, 2011 Earlier studies showed that the intensity of cyclic conjugation in the central ring R of perylene can be significantly altered by means of benzo-annelation. In particular, linear (resp. angular) benzoannelation was found to decrease (resp.

Beilstein Journal of Organic Chemistry, 2023 A set of novel 1,4-diaryl-1,3-butadiynes terminated by two 7-(arylethynyl)-1,8-bis(dimethylamino)naphthalene fragments was prepared via the Glaser–Hay oxidative dimerization of 2-ethynyl-7-(arylethynyl)-1,8-bis(dimethylamino)naphthalenes.

Stability of bicalicene isomers: A topological study [PDF]
Journal of the Serbian Chemical Society, 2016 Bicalicene is the conjugated hydrocarbon obtained by joining two calicene fragments. This can be done in two different ways, thus resulting in two bicalicene isomers (tentatively referred to as cis and trans).

Topological properties of altan-benzenoid hydrocarbons [PDF]
Journal of the Serbian Chemical Society, 2014 The main topological characteristics of altan-benzenoids are established. In particular, it is shown that the perimeter of Kekuléan altan-benzenoids is of size 4k , having a destablizing (antiaromatic) energy effect, similar to (4k)-annulenes.

A simple mathematical model for the effect of benzoannelation on cyclic conjugation [PDF]
Journal of the Serbian Chemical Society, 2011 In a series of earlier studies, it was established that benzoannelation in the angular (resp. linear) position relative to a ring R of a polycyclic conjugated π-electron system, increases (resp.

Enantioselective Conjugate Allylation of Cyclic Enones [PDF]
The Journal of Organic Chemistry, 2011 Enantioselective organocatalytic 1,2-allylation of a cyclic enone followed by anionic oxy-Cope rearrangement delivered the ketone as a mixture of diastereomers. This appears to be a general method for the net enantioselective conjugate allylation of cyclic enones.

Expansivity and Roquette Groups [PDF]
, 2014 One looks at expansive subgroups in particular examples of Roquette groups. This study is motivated by the importance of expansive subgroups in the theory of stabilizing bisets highlighted in [BouThe].
