Reactions of Aromatic Compounds
If mercuration under the homogeneous conditions described above is brought
about essentially by acetoxymercury perchlorate ion pairs then the ratio k°,,s(Hg"]
/ [I-IgOAc"ClOZ ] should be constant but this was found not to be the case, ...

Homolytic Aromatic Substitution: International Series of ...
The possibility exists, therefore, that under the opposite conditions, viz. those of “
classical” mercuration, a much less selective reagent, which may be homolytic, is
responsible for the reaction. Indeed the results of Jackson and Frant (1955) ...

In all cases the selectivity appears to decrease with increasing reactivity,
although the analysis is considerably complicated by uncertainty as to the exact
nature of the attacking reagent in some cases. For example, in the mercuration
reaction ...

7.4.5.2 Comparison of the Activation Barriers for Mercuration and Thallation The
kinetic studies also establish the neutral HgtC^CCFsh and the cationic
TKChCCFsh* to be the principal electrophiles in mercuration and thallation,95

Nevertheless, the thiazole nucleus is not very reactive since 4-methylthiazole and
2,5-dimethylthiazole are inert in dilute sulfuric acid with bromine (229-231). B.

Aromatic and Heteroatomic Chemistry
The use of triphenylmethyl-lithium to determine the kinetic acidities of thiophen
and selenophen shows that the latter has the higher acidity, in agreement with an
earlier indication from base-catalysed hydrogen exchange.87 Mercuration.

Aromatic and Heteroaromatic Chemistry
The reaction occurs in three steps: mercuration (rate- limiting),
nitrosodemercuration, and oxidation of nitroso- to nitro-toluenes.106 Other Metal
