I found the field of Chemistry very interesting. Saw the article Phosphine ligands in the ruthenium-catalyzed reductive amination without an external hydrogen source published in 2021.0. Category: indole-building-block, Reprint Addresses Chusov, D (corresponding author), Russian Acad Sci, AN Nesmeyanov Inst Organoelement Cpds, Vavilova St 28, Moscow 119991, Russia.; Chusov, D (corresponding author), Natl Res Univ Higher Sch Econ, Miasnitskaya Str 20, Moscow 101000, Russia.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
A systematic study of the phosphine additives influence on the activity of a ruthenium catalyst in reductive amination without an external hydrogen source was carried out. [CymeneRuCl(2)](2) was used as a reference catalyst, and a broad set of phosphines including Alk(3)P, Alk(2)ArP, Ar3P and X3P was screened. Three complexes of general formula (Cymene)RuCl2PR3 were isolated in a pure form, and their catalytic activity was compared with the in situ generated complexes. Nonhindered triarylphosphines with electron acceptor groups were found to be the most perspective activating agents, increasing the activity of the catalyst approx. six times, Alk(2)ArP ligands have less noticeable influence, while trialkylphosphines strongly deactivate the ruthenium catalyst.
