The empty pz-orbital of a three-coordinate organoboron compound leads to its electron-
deficient properties, which make it an excellent π-acceptor in conjugated organic …

This review covers all aspects of 9-borafluorene chemistry, from the first attempted synthesis
in 1960 to the present. This class of molecules consists of a tricyclic system featuring a …

Homoatomic triple bonds between main-group elements have been restricted to alkynes,
dinitrogen, and a handful of reactive compounds featuring trans-bent heavier elements of …

The effects of different electronic and structural factors in determining the Lewis acidity of
boron compounds are analyzed. Scales of Lewis acidity for boron Lewis acids based on the …

The incorporation of boron into the core structure of fused polycyclic aromatics generates
compounds with highly attractive properties that have recently received significant attention …

(Hetero) arene-fused boroles are a class of compounds containing a 5-membered boron
diene-ring. Based on their molecular framework, the (hetero) arene-fused boroles can be …

The straightforward palladium-catalyzed synthesis protocol toward spiro-fused perylene
diimides is developed. The reaction involves two palladium-catalyzed C–H activations and 4 …

The choice of backbone linker for two ortho-bis-(9-borafluorene) s has a great influence on
the LUMO located at the boron centers and, therefore, the reactivity of the respective …

A two-step synthesis sequence furnishes quadruply annulated borepins in high yields. The
first step involves a nucleophilic substitution reaction between aryl–BF3K salts (aryl= mesityl …

Conjugated boron heterocycles have emerged as attractive synthetic targets due to their
potential in medicinal chemistry and as electronic materials. However, the development of …
