There is probably no other single molecule that has fascinated experimental and theoretical chemists so consistently over the past 40 years as has cyclobutadiene (CBD). On average, 16 publications which deal, in one form or another, with the parent compound C4H4 and 40 which deal with cyclobutdienes in general have appeared in every year of this time span, and there are probably many more on derivatives and metal complexes. There is no sign that interest in CBD is about to wane, as the highest… Expand
Unraveling the stability of cyclobutadiene complexes using aromaticity markers.
TLDR
This intriguing reversal of aromaticity from antiaromatic to aromatic terrain during the complexation process cannot be appropriately handled with single-reference-based theoretical techniques and is explored by a detailed aromaticity analysis using magnetically induced current densities (MICD) and nucleus independent chemical shifts (NICS) using genuine ab initio multi-reference wavefunction-based theory.

Recent Studies on the Aromaticity and Antiaromaticity of Planar Cyclooctatetraene
TLDR
In this review, recent theoretical and experimental studies on the antiaromaticity of hypothetical and actual planar COT are highlighted and theoretically predicted triplet aromaticity and stacked aromaticity of planarCOT are briefly described. Expand
Difluorobenzocyclooctyne: Synthesis, Reactivity, and Stabilization by β-Cyclodextrin
TLDR
It is found that the rate constant for the cycloaddition reaction of DIFBO with an azide exceeds those for difluorinated cyclooctyne (DIFO) and dibenzocyclooCTyne (DIBO). Expand
4π‐Electron B–N Monocycles: Stability and (Anti)aromaticity
This is a theoretical (DFT) study of the impact of electronic structural changes, induced by B–N/C–C isosterism, on two basic properties of 4π-electron antiaromatic system, that is, stability andExpand
Aromaticity of metallabenzenes and related compounds.
TLDR
This review focuses on the aromaticity of a particular family of organometallic compounds known as metallabenzenes, which are characterized by the formal replacement of a CH group in benzene by an isolobal transition metal fragment. Expand
Effects of ethynyl substitution on cyclobutadiene.
TLDR
The effects of ethynyl substitution on cyclobutadiene are explored via density functional theory and coupled-cluster calculations and a hyperhomodesmotic equation is used to assess the stabilization enthalpies of tetra-substituted singlet cyclobUTadienes. Expand

On the σ,π-energy separation of the aromatic stabilization energy of cyclobutadiene
The separation of the aromatic stabilization energy (ASE) of cyclobutadiene (CBD) into a σ- and a π-component is reinvestigated. Eight different reactions are considered for this purpose. AsExpand
The effect of two types of dibenzoannulation of pentalene on molecular energies and magnetically induced currents.
TLDR
The effect of two types of dibenzo-fusion of pentalene in the singlet and triplet states on its molecular energies and magnetically induced ring currents was examined via density functional calculations and revealed that the π-electronic system is the most important factor controlling the molecular energies.

Experimental determination of the antiaromaticity of cyclobutadiene
TLDR
Photoacoustic calorimetry was used to quantify the antiaromaticity of 1,3-cyclobutadiene by measuring the heat release accompanying its formation via photofragmentation of a polycyclic precursor, providing an enthalpy of formation for CBD of 114 +/- 11 kilocalories per mole. Expand

An energetic measure of aromaticity and antiaromaticity based on the Pauling-Wheland resonance energies.
TLDR
The "extra cyclic resonance energy" (ECRE) is derived to characterize and measure the extra stabilization (aromaticity) of conjugated rings and correlates well with nucleus-independent chemical shift (NICS) and other quantitative aromaticity criteria. Expand
Nucleus-Independent Chemical Shifts:  A Simple and Efficient Aromaticity Probe.
TLDR
The use of absolute magnetic shieldings, computed at ring centers with available quantum mechanics programs, are proposed as a new aromaticity/antiaromaticity criterion to establish NICS as an effective aromaticity criterion. Expand

Strain energy of small ring hydrocarbons. Influence of C-h bond dissociation energies.
TLDR
Ab initio calculations at the G2, G3, and CBS-Q levels of theory have been applied to the question of the origin of ring strain in a series of unsaturated hydrocarbons, indicating a general trend that suggests that the increased ring strain (SE) of uns saturated small ring alkenes may be attributed in part to their relatively weak allylic C-H bonds.
