Synthetic Route of 141-30-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Article，once mentioned of 141-30-0

A new generation of double pyridazine molecular rotors differing in intramolecular dipole-dipole spacing was synthesized. All rotor molecules formed bulk inclusions in a tris(o-phenylenedioxy)cyclotriphosphazene (TPP) host. Results of dielectric spectroscopy were fitted to a pair of nine-state models that accounted for interactions of neighboring dipoles at either an aligned or opposed possible orientation of the local threefold dipole rotation potentials within a channel of the TPP host. The results indicate dipole-dipole interaction strengths at the 100 to 200 K scale that lead dipoles to preferentially populate a subset of low-energy configurations. They also reveal that pyridazines with ethynyl substituents in 3- and 6-positions have slightly higher rotational barriers (3.2-3.5 kcal/mol) than those carrying one ethynyl and one tert-butyl group (1.9-3.0 kcal/mol). Upon cooling, these barriers reduce the rate of thermal transitions between the potential wells so much that the inclusions cannot achieve ordered dipolar ground states.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of 6-Methylpyridazin-3(2H)-one, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 13327-27-0, Name is 6-Methylpyridazin-3(2H)-one, molecular formula is C5H6N2O

1,3-Dipolar cycloadditions of diazoalkanes to pyridazin-3(2H)-ones 1-7 and pyridazin-3(2H)-thiones 8 and 9 are regioselective producing 3H-pyrazolo<3.4-d>pyridazin-4(5H)-ones 15-19, 27-29 and 34-38 as the major products.In some instances, the isomeric 3H-pyrazolo<3.4-d>pyridazin-7(6H)-ones, such as 20 and 23 were isolated as the minor products.From 3 and 6 the primary 3a,7a-dihydro cycloadducts 25 and 26, and rearranged 1,2-dihydro intermediate 31 were isolated.From 10 and 1-diazoindane the isomeric exo- and endo-spiro products 39 and 40 were formed.

A kinetic study has been made of the first-order thermal decomposition of the title compounds into ethylene and the corresponding aza-substituted pyridines, between 650 and 713 K.The relative elimination rates at 650 K are (2-ethoxypyridine = 1): 0.545, 10.0, 1.03, 1.12, 9.68, and 3.28, respectively.The electronic effects of the aza ‘substituent’ are small, and a more important factor appears to be the C-N ?-bond order; this latter accounts for the high reactivity of the pyridazines.The effects of the chloro substituent and of the aza ‘substituent’ are explicable in terms of a balance between electron withdrawal from the C-O bond (producing deactivation) and from the nitrogen involved in the cyclic transition state (producing deactivation).The effects of the chloro substituents confirm that the most important step of the reaction is breaking of the C-O bond.The statistically corrected rate (per ring nitrogen) of 2-ethoxypyrimidine is unexpectedly low.This may reflect difficulty in achieving the coplanar transition state in which the lone pairs in the s-orbitals of oxygen and the nitrogen not involved in the elimination are brought into close proximity.
