The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 1078-61-1, Name is 3-(3,4-Dihydroxyphenyl)propionic acid, SMILES is O=C(O)CCC1=CC=C(O)C(O)=C1, in an article , author is Bodman, Samantha E., once mentioned of 1078-61-1, Formula: https://www.ambeed.com/products/1078-61-1.html.
The reaction of ligands based on 3,6-di(2-pyridyl)pyridazine with symmetrical carbocyclic rings fused to the pyridazine ring; 7,10-di(2-pyridyl)-8,9-diazafluoranthene (L-1), 1,4-di(2-pyridyl)-6,7,8,9-tetrahydro-5H-cyclo-hepta[d]pyridazine (L-2), 1,4-di(2-pyridyl)-5,6,7,8-tetrahydro-phthalazine (L-3), 1,4-di(2-pyridyl)-6,7-dihydro-5H-cyclo-penta[d]pyridazine (L-4) with silver salts gave a series of complexes (1-7). Characterisation of these using single crystal X-ray structure determination clearly showed that the steric bulk of the carbocycle affects the degree to which pyridine groups remain co-planar with pyridizine, and hence their ability to chelate. The more hindered ligands L-1-L-3 form a mixture of bischelating and tetrabridging, while the least hindered (L-4) was able to chelate exclusively. In the case of L-4, the nature of the anion and solvent were also able to affect the outcome of the reaction, with tetrafluoroborate giving the first example of a 4,5-substituted 3,6-di(2-pyridyl) pyridazine ring forming a [2 x 2]-grid.
