Reactive intermediates as recognized chemical entities date back for over a century, and
among the earliest examples were simple free radicals, as identified in 1879, when it was …

Ketenimines are an important class of reactive species and useful synthetic intermediates.
During the last two decades several practical and versatile approaches to ketenimines have …

Rhodium catalysis: A highly efficient and general method has been established to prepare
cinnolines, cinnolinium salts, and polycyclic cinnolinium salts through the rhodium (III) …

A simple and concise method for the synthesis of cinnolines has been developed by the
reactions of readily available enaminones and aryl diazonium tetrafluoroboronates. The …

Reported herein is a novel [5+ 1] cycloaddition–aromatization of benzotriazoles and sulfur
ylides to efficiently construct 1, 2, 4-benzotriazine derivates with good yield. This new …

Transition metal-catalyzed C–H annulation reactions have been extensively utilized for the
synthesis of cinnolines, especially the N-protected ones; however, none of them can yield …

Cumulenes, including allene, ketenimine, and ketene, can be employed as dienophiles in
Diels–Alder type reactions. The activation energies of a Diels–Alder reaction between …

A wide range of benzo [c] cinnolines are prepared through a sequential C–C and C–N bond
formation by means of an oxidative C–H functionalization. The reaction proceeds via the C …
