Zhang, Kan; Yao, Yanxiu; Sun, Wenjin; Wen, Rui; Wang, Yanyan; Sun, Huaming; Zhang, Weiqiang; Zhang, Guofang; Gao, Ziwei published an article in 2021. The article was titled 《Triazine-wingtips accelerated NHC-Pd catalysed carbonylative Sonogashira cross-coupling reaction》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).Formula: C7H7IO The information in the text is summarized as follows:
By using a ppm-level precatalyst T-NHC-Pd, the highly efficient coupling of aryl iodide, alkyne and carbon monoxide furnished a variety of ynone compounds T-NHC-Pd, which deprotonated 4-methyl-phenylacetylene under mild conditions, converted into alkynyl-coordinated catalytic active species PdCl(T-NHC)(Py)(alkynyl). In the putative Pd/Pd catalytic cycle, both triazine-wingtips and NHCs were key players for establishing the carbonylative cross-couplings with high TON and TOF. After reading the article, we found that the author used 1-Iodo-2-methoxybenzene(cas: 529-28-2Formula: C7H7IO)
1-Iodo-2-methoxybenzene(cas: 529-28-2) participates in palladium catalyzed enantioselective Heck arylation of 2,3-dihydrofuran in the presence of chiral ionic liquids containing L-prolinate and L-lactate anions and non-chiral quaternary ammonium cations.Formula: C7H7IO
