Synthesis of polyfluoroalkyl substituted cyclopropane derivatives was written by Wu, Fan-Hong;Gu, Song;Huang, Wei-Yuan. And the article was included in Youji Huaxue in 2006.Product Details of 17920-23-9 This article mentions the following:
A new convenient synthesis of a series of polyfluoroalkyl substituted cyclopropane derivatives was achieved by the reaction of polyfluoroalkyl iodides with di-Et (allyl)malonate in the presence of sodium dithionite in 45-55% yields. The reaction of allyl acetoacetate with polyfluoroalkyl iodides under similar conditions gave the corresponding adducts. Treatment of the latter with base gave the desired cyclization products, such as, for example, 2-(3-chloro-2,2,3,3-tetrafluoropropyl)-1,1-cyclopropanedicarboxylic acid di-Et ester. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Product Details of 17920-23-9).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 17920-23-9
