Regiospecific Synthesis of Bicyclo- and Heterobicyclo-gem-difluorocyclobutenes Using Functionalized Fluoroallenes and a Novel Mo-Catalyzed Intramolecular [2 + 2] Cycloaddition Reaction was written by Shen, Qilong;Hammond, Gerald B.. And the article was included in Journal of the American Chemical Society in 2002.Computed Properties of C10H14O4 This article mentions the following:
The synthesis of functionalized gem-difluoroallenes served as a platform for an unprecedented molybdenum-catalyzed intramol. allene-alkyne [2+2]-cycloaddition that produced difluorobicyclooctadienes, a hitherto unknown class of bicyclo- and heterobicyclo-CF2-containing cyclobutenes. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Computed Properties of C10H14O4).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Computed Properties of C10H14O4
