In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 141-30-0, name is 3,6-Dichloropyridazine, introducing its new discovery. Formula: C4H2Cl2N2
The syntheses of new pyridazinethiocarboxamides are described using the reaction of Lawesson’s reagent with pyridazine carboxamides or by reacting lithiopyridazines with phenylisothiocyanate. Metalation of 3-N-tert-butylpyridazinethiocarboxamides and carboxamides with LTMP followed by reaction of the lithio derivatives with various electrophiles gave access to a wide range of polysubstituted pyridazines. An unexpected regioselectivity at the meta position of the thiocarboxamide group was observed and explained.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 141-30-0, and how the biochemistry of the body works.Formula: C4H2Cl2N2
