Mitrofanov, A. Yu. published the artcileCu(I) complexes with diethoxyphosphoryl-1,10-phenanthrolines in catalysis of C-C and C-heteroatom bonds formation, Safety of Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), the publication is Inorganica Chimica Acta (2015), 297-301, database is CAplus.
Diethoxyphosphoryl substituted 1,10-phenanthroline Cu(I) complexes were tested as catalysts in the Sonogashira-type reaction, α-arylation of phosphoryl-stabilized C-H acids, C-N, C-P bond forming reactions (substitution reactions) and in the reaction of phenylacetylene and bis(pinacolato)diboron (addition reaction). The complexes demonstrate fairly high catalytic activity and in some cases their efficiency is superior to that of the parent Cu(phen)(PPh3)Br (phen = phenanthroline).
Inorganica Chimica Acta published new progress about 25753-84-8. 25753-84-8 belongs to bromides-buliding-blocks, auxiliary class Copper, name is Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), and the molecular formula is C30H24BrCuN2P, Safety of Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I).
