Electric Literature of 53896-49-4, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.53896-49-4, Name is Pyridazine-3-carbonitrile, molecular formula is C5H3N3. In a article，once mentioned of 53896-49-4
Irradiation of 9 leads to hydrogen abstraction by N(1) and fragmentation to 8 from a triplet with ET ?78 kcal/mol. Irradiation of 2-acylpyridines (10) leads to abstraction by both nitrogen and oxygen (cf. eq 4), with the same Stern-Volmer kqtau for the two processes. Irradiation of 2-acylpyrazines (11) can lead to abstraction by either nitrogen (phi27 0.77 from 11b) or oxygen (phi11a 0.95 from 11f)- 3-Acylpyridazine 12d is unreactive on direct irradiation or triplet sensitization with sensitizer ET ?70 kcal/mol; it furnishes a small amount of 12a on sensitization by acetone. Ketone 18 is recovered unchanged from irradiation under all conditions used with 12d. These observations suggest a correlation between the photochemistry of each of these compounds and the energy of the npi* triplet of the heteroaromatic ring. The nature of the excited state(s) responsible for hydrogen abstraction by nitrogen and oxygen in these ketones is discussed.
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 53896-49-4
