Reference of 4721-98-6, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4721-98-6, Name is 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline, molecular formula is C12H15NO2. In a Article，once mentioned of 4721-98-6
The asymmetric hydrogenation of cyclic ketimines, 1-alkyl-3,4-dihydroisoquinolines 5a,b was carried out with diphosphine-iridium(I) complex catalysts in the presence of various imides or amides as a co-catalyst. Remarkable effects of five-membered imides on the enantioselectivity and the catalytic activity were observed. The enantioselectivity with a BCPM 1-iridium(I) complex was much improved up to 93% ee by addition of phthalimide.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 4721-98-6. In my other articles, you can also check out more blogs about 4721-98-6
