Stereoisomerization of Hexacoordinate Sulfur and Tellurium
… Calorimetry showed the trans-to-cis isomerization to be exothermic by 1.6 (+OR-) 0.5 kcal/mol. The rapid, acid-catalyzed isomerization of trans isomer 2 to give cis isomer 3 occurs by a dissociative mechanism through a pentacoordinate cationic sulfur intermediate, a 10-S-5 …

Mechanisms of Methoxide Ion Substitution and Acid- Catalyzed Z/E Isomerization of N-Methoxyimines
… ethyl cyanoacetate, and diethyl malonate. Acid-catalyzed isomerization of compounds containing the O-methyloxime moiety have been investigated with ab initio calculations (HF/6-31+G*, MP2/6- 31+G*//HF/6-31+G*, B3LYP/6-31+G*//HF/6-31+G*). Barriers for rotation around the C-N bond following …

Electronic Spectroscopy, Photochemistry, And Reactivity Of Isoprene-Derived Criegee Intermediates
… reactions of MVK-oxide with SO2, formic acid, and water vapor under thermal conditions. Complimentary experiments using multiplexed photoionization mass spectrometry (MPIMS) identify products resulting from reaction of MVK-oxide with SO2 and formic acid. The reaction of MVK-oxide with …
