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...

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

undergo a [3+2] dipolar cycloaddition with the aryne to give the product, or a [3+2] annulation with aryne which would also give the final product. While...

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

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...

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...

label was used to determine the mechanism in the 1,2- to 1,3-didehydrobenzene conversion of the phenyl substituted aryne precursor 1 to acenaphthylene....

transition-metal-free carbon-carbon and carbon-heteroatom bond-forming reactions using aryne chemistry and carbene-based organocatalysis. Biju has a B Sc degree in chemistry...

occupied by the leaving group. For example, cine-substitution is observed in aryne chemistry. Tele-substitution occurs when the new position is more than one...

bromine substituent replaced by an amine. This rules out the formation of an aryne intermediate A which would also give the 5-substituted isomer. The exclusion...
