1原位生成的Ph_3C^+均相有机催化剂催化4,4'-芳亚甲基-二(3-甲基-1-苯基-1H-吡唑-5-醇)高效合成(英文)显示文摘Trityl chloride(Ph3CCl) efficiently catalyzes the condensation of 3‐methyl‐1‐phenyl‐1H‐pyrazol‐ 5(4H)‐one and aromatic aldehydes under mild and solvent‐free conditions, affording 4,4'‐(arylmethylene)‐ bis(3‐methyl‐1‐phenyl‐1H‐ pyrazol‐5‐ol)s in high to excellent yields and in short reaction time. The presence of the requisite organocatalytic trityl carbocation(Ph3C+) species was confirmed by analysis of infrared, 1H NMR, and ultra violet spectral data. A plausible mechanism was proposed for the reaction based on the observations and literature precedent.Abdolkarim Zare Maria Merajoddin Ahmad Reza Moosavi‐Zare Mahmoud Zarei 2014催化学报2014,35,1:0
