Pihlaja, Kalevi published the artcileCarbon-13 nuclear magnetic resonance studies on saturated heterocycles. Part I. Substituent effects on the carbon-13 chemical shifts of methyl-substituted 1,3-dioxolanes, Formula: C6H12O2, the publication is Finnish Chemical Letters (1977), 141-3, database is CAplus.
The 13C chem. shifts for 1,3-dioxolane and eleven Me-substituted derivatives are reported. The magnitude of the substituent effects, compared with those for cyclopentane and 1,3-dioxane, indicate that the 1,3-dioxolane ring is a dynamic mixture of conformations and that only 2,2-di-Me substitution shows increased steric demands.
Finnish Chemical Letters published new progress about 1193-11-9. 1193-11-9 belongs to dioxole, auxiliary class Dioxolanes, name is 2,2,4-Trimethyl-1,3-dioxolane, and the molecular formula is C6H12O2, Formula: C6H12O2.
