108-47-4, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 108-47-4, Name is 2,4-Dimethylpyridine,introducing its new discovery.
The 13C n.m.r. spectra of a series of nitrogen-containing aromatic compounds have been simulated by using parametric techniques.The observed chemical shifts were related to numerically encoded structural parameters, called descriptors.The electronic and geometric descriptors were calculated after optimization of the molecular structures by using the MNDO semiempirical method.Subsequently, the method of stepwise, multiple linear regression was used to calculate coefficients relating the descriptors to the observed chemical shifts.This study involves 32 compounds such as pyridine, pyrimidine, triazine, pyridazine, and their methyl derivatives.Plotting of experimantal against calculated chemical shifts for 23 carbon centres in the prediction set of five compounds shows a standard deviation of 1.41 ppm and a correlation coefficient of 0.999.
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 amount108-47-4, you can also check out more blogs about108-47-4
