In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Reference of 141-30-0, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 141-30-0, name is 3,6-Dichloropyridazine. In an article，Which mentioned a new discovery about 141-30-0
Metalation, pyradazines, lithiation Starting from 3,6-dichloropyridazine, a series of new pyridazines bearing lithiation-directing groups in alpha-position to a ring nitrogen atom (compounds 1-5) was prepared. Metalation employing lithium alkylamides was found to afford ortho-substituted pyridazines. The regioselectivity, depending on the nature of the metalating agent, is discussed.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 141-30-0.Reference of 141-30-0
