This review has been centralized on applications of phthalic anhydride (PA) as a valuable
and significant heterocyclic substrate in two-and multicomponent organic reactions. The …

In recent years, decarbonylative annulation reactions have emerged as one of the most
efficient routes to construct a variety of important carbocyclic and heterocyclic scaffolds. The …

Disclosed herein is the design of an unprecedented electrophilic rhodium enalcarbenoid
which results from rhodium (II)‐catalyzed decomposition of a new class of enaldiazo …

A nickel/NHC system for regioselective oxidative annulation by double C− H bond activation
and concomitant alkyne insertion is described. The catalytic reaction requires a bidentate …

Direct homologation of aromatic amides with internal alkynes has been accomplished via a
nickel-catalyzed sequential C–H activation reaction. The use of a rigid chelating group and a …

Reliable and short synthetic routes to polycyclic aromatic hydrocarbons and nanographenes
are important in materials science. Herein, we report an efficient one‐step annulative π …

A palladium-catalyzed decarbonylative annulation of 2-arylbenzoic acids with internal
alkynes via C (sp2)–H activation has been developed. A series of phenanthrenes were …

ortho-Substituted aryl boronates are introduced as aryne precursors for transition-metal-
catalyzed transformations. On treatment with t BuOK and Pd (0), metal-bound aryne …

An efficient [2+ 2+ 2] benzannulation of phthalic acids/anhydrides with two alkynes was
developed for synthesis of multisubstituted 1-naphthoic acids via Ru-catalyzed C–H …

A novel strategy is developed for the synthesis of dibenzopleiadiene-embedded polycyclic
aromatic hydrocarbons from 1, 8-naphthalic anhydride derivatives and cyclic diaryliodonium …
