The article conveys some information:
The cross-coupling study of gem-dibromoesters with triarylbismuths as threefold arylating reagents was investigated under palladium-catalyzed conditions. This study using triarylbismuth reagents explored the cross-coupling reactivity with various functionalized gem-dibromoesters. It furnished a variety of multi-functional trisubstituted acrylates embedded with aryl, alkene and alkyne scaffolds in high yields. The present study in turn, provided easy access to various triarylated acrylates and functionalized 1,3-dienyl and 1,3-enyne esters. Further, the established method applied in the step-economic and convergent synthesis of quebecol (I) natural product in good yield. In the experimental materials used by the author, we found Ethyl oxalyl monochloride(cas: 4755-77-5Product Details of 4755-77-5)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Product Details of 4755-77-5
