Reference of 161265-03-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine). In a document type is Article, introducing its new discovery.
The alkoxycarbonylation of alpha-chloro ketones with carbon monoxide in alcoholic solvents could be optimized to generate beta-keto esters in high yields using much lower catalyst loadings than previously reported in the literature. Among the different screened parameters, the nature of the ligand proved to be the most crucial one, the Xantphos ligand affording the highest yields. The scope of the reaction could then be extended to a wide variety of chloro ketones with different types of alcohols. Copyright
