Arbaciauskiene, Egle; Martynaitis, Vytas; Krikstolaityte, Sonata; Holzer, Wolfgang; Sackusa, Algirdas published an article in 2011, the title of the article was Synthesis of 3-substituted 1-phenyl-1H-pyrazole-4-carbaldehydes and the corresponding ethanones by Pd-catalyzed cross-coupling reactions.Reference of 3-(Naphthalen-2-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde And the article contains the following content:

An efficient synthetic route to construct substituted 1-phenyl-1H-pyrazole-4-carboxaldehydes and the corresponding ethanones was described and the synthesis of the target compounds was achieved using 1-phenyl-1H-pyrazol-3-ol as a starting material. Carbon-carbon bond-forming palladium-catalyzed cross-coupling reactions were applied for the functionalization of the intermediate pyrazole triflates [i.e., trifluoromethanesulfonic acid 1-phenyl-1H-pyrazol-3-yl ester derivatives]. The target compounds thus formed included imidazo[4,3-c]pyridine derivatives, 1,3-diphenyl-1H-pyrazole-4-carboxaldehyde, 1-phenyl-3-(3-thienyl)-1H-pyrazole-4-carboxaldehyde, 1-(1,3-diphenyl-1H-pyrazol-4-yl)ethanone, etc. The experimental process involved the reaction of 3-(Naphthalen-2-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde(cas: 36640-53-6).Reference of 3-(Naphthalen-2-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde
