Nitration, nitrosation, azo coupling, halogenation, sulfonation, formylation, hydroxymethylation, and aminomethylation have been observed with substituted pyrimidines.
32.
This is done by catalysis using RebH in vitro halogenation and RebF ( a flavin reductase ) to provide FADH2 for the halogenase.
33.
It is possible to predict the results of a halogenation reaction based on bond dissociation energies and the relative stabilities of the radical intermediates.
34.
In acidic solution, usually only one alpha hydrogen is replaced by a halogen, because each successive halogenation is slower than the first.
35.
:Halogenation of Benzene where X is the halogen, catalyst represents the catalyst ( if needed ) and HX represents the protonated base.
36.
The heme-containing chloroperoxidase ( CPO ) exhibits peroxidase, catalase and cytochrome P450-like activities in addition to catalyzing halogenation reactions.
37.
The pathway and stoichiometry of halogenation depends on the structural features and functional groups of the organic substrate, as well as on the specific halogen.
38.
What differentiates a halogenated ether from other types of ethers is the substitution ( halogenation ) of one or more hydrogen atoms with a halogen atom.
39.
Peroxides mainly work as radical initiators for things like radical halogenation and other reactions, because of the homolytic cleavage of the O-O single bond.
40.
Oxidative halogenation can be promoted by CAN as an " in situ " oxidant for benzylic bromination, and the iodination of ketones and uracil derivatives.
