Most of the chemical and biological processes involving the fixation and transformation of
small molecules have long been exclusive for metal complexes. Meanwhile, the last …

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

C–C bond coupling reactions illustrate the wealth of organic transformations, which are
usually mediated by organotransition metal complexes. Here, we show that a borafluorene …

As the models for studying defected graphene, π‐conjugated systems containing
heptagonal rings have attracted increasing interest due to their dynamic behaviors …

The reactions of 9-borafluorenes with organic azides result in either the insertion of the α-
nitrogen and elimination of N2 or the insertion of the γ-nitrogen to generate the …

Direct insertion of unsaturated substrates into a five‐membered borole ring is a useful
method to obtain valuable heterocycles containing one or more three‐coordinate boron …

The synthesis of 1, 2-oxaborines is accomplished via the reaction of pentaarylboroles with N-
methylmorpholine-N-oxide via a 1, 1-insertion reaction. The aromatic nature of 1, 2 …

The reactivity of 9-phenyl-9-borafluorene with a series of 1, 2-dipolar organic molecules is
investigated, revealing that either adducts or seven-membered heterocycles are generated …

The first examples of Lewis base adducts of the parent boraphosphaketene (H2B‐PCO) and
their cyclodimers are prepared. One of these adducts is shown to undergo mild …

We recently reported a new one‐pot transformation of alkynes into 9, 10‐
diarylphenanthrene derivatives, which proceeds through efficient catalyst‐free 1, 2 …
