Dienediolates of unsaturated carboxylic acids in synthesis. Aldehydes and ketones from alkyl halides, by ozonolysis of β,γ-unsaturated α-alkyl carboxylic acids. The role of a tertiary amine in the cleavage of ozonides was written by Aurell, Maria Jose;Ceita, Luisa;Mestres, Ramon;Tortajada, Amparo. And the article was included in Tetrahedron in 1997.Formula: C7H13ClO2 This article mentions the following:
A convenient two-step procedure for a two carbon homologative conversion of alkyl halides into aldehydes and Me ketones by α-alkylation of unsaturated carboxylic acids, followed by ozonolysis is developed and applied to the synthesis of ω-chloro aldehydes. Triethylamine is superior to di-Me sulfide or triphenylphosphine for cleavage of the ozonides, except when aldol condensation side reactions require use of protic solvents and iodide salts. Cleavage of the ozonides by triethylamine is shown to occur mainly through a reductive process. In the experiment, the researchers used many compounds, for example, 2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0Formula: C7H13ClO2).
2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0) 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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Formula: C7H13ClO2
