category: chiral-nitrogen-ligands, 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.
A novel iron-catalyzed alkenylation of 2-substituted azaarenes through sp3 C-H bond activation has been developed. A favorable E2-elimination is proposed as a key step to cleavage of C-H and C-N bonds for the construction of a C=C bond in high stereoselectivity. This transformation represents an efficient way to synthesize 2-alkenylated azaarenes from simple starting materials.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. category: chiral-nitrogen-ligands, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108-47-4, in my other articles.
