Because a catalyst decreases the height of the energy barrier, 108-47-4, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.108-47-4, Name is 2,4-Dimethylpyridine, molecular formula is C7H9N. In a article£¬once mentioned of 108-47-4
Metal- and base-free regioselective thiolation of the methyl C(sp3)-H bond in 2-picoline: N -oxides
A one-pot, two-step synthesis of pyridine-2-ylmethyl thioethers is developed through a TFAA-mediated [3,3]-sigmatropic rearrangement of pyridine N-oxides and TBAB-catalyzed direct conversion of trifluoroacetates into thioethers under metal- and base-free conditions. This methodology enables thiolation of the unactivated methyl C(sp3)-H bond in 2-picolines with thiols. Remarkable features of the method include high regioselectivity, step- and atom-economy, mild conditions, simple operation, wide substrate scope and scalability. Furthermore, the method has been successfully applied to the synthesis of omeprazole sulfide and rabeprazole sulfide without the need for TBAB catalysis. A comprehensive green chemistry metrics analysis indicated that this method is much more efficient and greener than the reported synthesis of rabeprazole sulfide.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 108-47-4, In my other articles, you can also check out more blogs about 108-47-4
