New discoveries in chemical research and development in 2021. In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Electric Literature of 22990-19-8, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 22990-19-8, name is 1-Phenyl-1,2,3,4-tetrahydroisoquinoline. In an article，Which mentioned a new discovery about 22990-19-8
Various 1-aryl-1,2,3,4-tetrahydroisoquinolineswere synthesized by coupling alpha-amino carbanions, derived from N-protected secondary amines, with in situ generated arynes. Different N-protecting/activating groups were investigated and it was found that only the N-bis(dimethylamino)phosphinoyl group is suitable to obtain the title compounds.This procedure has also been used for an efficient one-pot synthesis of the drug (±)-FR115427.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 22990-19-8
