PVC-NHC-Pd(0): An efficient and reusable heterogeneous catalyst for highly cis-selective semi hydrogenation of alkynes using formic acid as hydrogen source was written by Zheng, Waner;Zhou, Yuemin;Li, Yiqun. And the article was included in Inorganic Chemistry Communications in 2021.HPLC of Formula: 39969-26-1 This article mentions the following:
PVC-NHC-Pd(0) catalyst was prepared and exerted to highly cis-selective semi hydrogenation of diarylacetylene using formic acid as hydrogen source under mild condition. The as-prepared catalyst was well characterized by various techniques such as FT-IR, 1H NMR, XRD, SEM, EDX, TEM, XPS, and TGA. The catalyst can be easily recovered and recycled without loss of its activity and selectivity owing to the metal-ligand interaction between Pd(0) with polymeric NHC ligands. This protocol is an attractive alternative of the classical Lindlar’s hydrogenation. In the experiment, the researchers used many compounds, for example, 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1HPLC of Formula: 39969-26-1).
1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.
