In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Application of 1121-79-5, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1121-79-5, name is 3-Chloro-6-methylpyridazine. In an article，Which mentioned a new discovery about 1121-79-5
3,4-Diaryl-4,5-dihydro-1H-pyrazole compounds having a selected 5- or 6-membered aromatic heterocyclic moiety in the 4-position and an optionally substituted phenyl moiety in the 3-position, such as 4,5-dihydro-3-(4-fluorophenyl)-4-(5-trifluoromethyl-2-pyridinyl)-1H-pyrazole were prepared as intermediates in the preparation of insecticidal 3,4,N-triaryl-4,5-dihydro-1H-pyrazole-1-carboxamide compounds. The 3,4-diaryl-4,5-dihydro-1H-pyrazole compounds can be prepared from appropriate 1,2-diarylethanone compounds by successive treatments with N,N,N’,N’-tetramethyldiaminomethane in dichloromethane in the presence of acetic anhydride (to form a Mannich adduct) and hydrazine in the presence of a catalytic amount of trifluoroacetic acid.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1121-79-5
