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

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...

- 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

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