In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3340-78-1, name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery.

Controllable Chemoselectivity in Visible-Light Photoredox Catalysis: Four Diverse Aerobic Radical Cascade Reactions
Reported is the controllable selectivity syntheses of four distinct products from the same starting materials by visible-light photoredox catalysis. By employing a dicyanopyrazine-derived chromophore (DPZ) as photoredox catalyst, an aerobic radical mechanism has been developed, and allows the reactions of N-tetrahydroisoquinolines (THIQs) with N-itaconimides to through four different pathways, including addition-cyclization, addition-elimination, addition-coupling, and addition-protonation, with satisfactory chemoselectivity. The current strategy provide straightforward access to four different but valuable N-heterocyclic adducts in moderate to excellent yields. Radical control: A radical mechanism for N-tetrahydroisoquinolines (THIQ) in the presence of oxygen was successfully accomplished by employing a dicyanopyrazine-derived chromophore (DPZ) as a photoredox catalyst. The substrates can undergo either addition-cyclization, addition-elimination, addition-coupling, or addition-protonation by judiciously regulating the reaction conditions. Four types of N-heterocycles are generated in moderate to excellent yields.
