As a widely existing functional group in organic molecules, the carboxyl group has
numerous advantageous characteristics such as great convenience for further …

The chemistry of nonalternant hydrocarbons has recently experienced a considerable
resurgence. As the relationship between naphthalene and azulene shows, an important …

Fluorescent materials of practical value have attracted considerable attention because of
their important applications in the fields of bioprobes, chemosensors, organic light-emitting …

The first planar π‐extended azulene that retains aromaticity of odd‐membered rings was
synthesized by [3+ 3] peri‐annulation of two naphthalene imides at both long‐edge sides of …

A new and convenient synthesis of aryl-substituted naphtho [2, 1-a] azulenes by the
combination of Suzuki–Miyaura, Sonogashira, and cycloisomerization reactions is reported …

A palladium-catalyzed [3+ 2] annulation of naphthalic anhydrides with internal alkynes has
been developed. The present protocol offers an efficient and convenient route to access a …

Ru (II)-catalysed oxidative (4+ 2) annulation of chromene and coumarin-3-carboxylic acids
with alkynes/propargylic alcohols via sp2 C–H bond activation is reported. While the …

A regioselective and chemodivergent synthetic approach for azulenolactones and
azulenolactams as a new scaffold was demonstrated through Rh (III)‐catalyzed reaction of N …

A rhodaelectro-catalyzed C2–H selectively decarboxylative alkenylation of 3-carboxy-1 H-
indoles employing electricity as the traceless terminal oxidant has been accomplished. The …

The first example of directed C–H activation for azulene is reported. A variety of 2-
arylazulenes are obtainable exclusively from 1-azulene carboxylic acids, with yields of up to …
