chemistry, arynes and benzynes are a class of highly reactive chemical species derived from an aromatic ring by removal of two substituents. Arynes are examples...

synthesis, methyl anthranilate can be used as a source of the highly reactive aryne, benzyne. It is obtained by diazotization of the amine group using sodium...

intermediates based on carbon are radicals, carbenes, carbocations, carbanions, arynes, and carbynes. Reactive intermediates have several features in common: low...

Transition metal benzyne complexes are organometallic complexes that contain benzyne ligands (C6H4). Unlike benzyne itself, these complexes are less reactive...

chloride reaction proceeds through a classical aryne intermediate: The isomers 1a and 1b form the same aryne 2 which continues to react to the anilines 3a...
