In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 2132-62-9 as follows. Formula: C16H14O2

General procedure: A mixture of acetophenone oxime 1a (0.2 mmol), diphenylacetylene 2 (0.24 mmol, 1.2 equiv), [Cp*IrCl2]2 (3 mol%), PivOH (0.06 mmol, 0.3 equiv), Cu(OAc)2. H2O (0.4 mmol, 2 equiv) and MeOH (2 mL) in a 15mL glass vial [sealed with poly(tetrafluoroethylene)(PTFE) cap] was heated at 120 C with vigorous stirring for 24 h. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, and filtered through Celite. The filtrate was concentrated in vacuo and purified by column chromatography on silica gel to give the corresponding product 4.

According to the analysis of related databases, 2132-62-9, the application of this compound in the production field has become more and more popular.
