Carbon-13 NMR study of the structures of some acyclic and cyclic ketene acetals was written by Taskinen, E.;Pentikainen, M. L.. And the article was included in Tetrahedron in 1978.Computed Properties of C4H7ClO2 This article mentions the following:
A 13C NMR study of the spatial structures of acyclic ketene acetals showed that the most stable rotamers of (MeO)2C:CH2 are s-cis,s-cis and s-cis,gauche, the former being the more stable, and that the relative stability of the s-cis,s-cis form for dialkyl ketene acetals decreased with increasing bulkiness of the alkyl groups. The conformations of 5- to 8-membered cyclic ketene acetals are discussed and compared with those of the corresponding cyclic vinyl ethers and hydrocarbons. In the experiment, the researchers used many compounds, for example, 2-Chloromethyl-1,3-dioxolane (cas: 2568-30-1Computed Properties of C4H7ClO2).
2-Chloromethyl-1,3-dioxolane (cas: 2568-30-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Computed Properties of C4H7ClO2
