Kinetics of Some Methylenecyclopropane Rearrangements

Intramolecular Steric Factors in the Thermolysis of 4-Alkylidine-1-pyrazolines

Secondary deuterium kinetic isotope effects and product proportions are measured for several methyl-substituted 4-methylene-1-pyrazolines and deuterated isotopomers.The kinetic data support a single-bond-cleavage mechanism, and the products indicate that three modes of ring closure are required.Evidence is presented for a series of monomethyl compounds to suggest that the mechanism is more complex than a two-step scheme would predict and that the interconversion of a series of intermediates 46 is required.

PROTON MOBILITY OF HYDROGEN IN SUBSTITUTED METHYLENECYCLOPROPANES AND VINYLCYCLOPROPANES

The kinetic acidities of methylenecyclopropane, 1,1-dicyclopropylmethylenecyclopropane, and 1-methyl-1-cyclopropylmethylenecyclopropane in the KCH2SOCH3-(CH3)2SO system were determined; the rate constants for the isomerization of the last hydrocarbon into 1,1-dicyclopropylethylene and of 1,1,dimethylmethylenecyclopropane into 1-methyl-1-cyclopropylethylene were also determined.The introduction of the vinyl group into the trimethylene ring and also the introduction of an exocyclic double bond lead to a marked increase in the proton mobility of the hydrogen.Electron-donating methyl and cyclopropyl groups at the double bond of methylenecyclopropane reduce its kinetic acidity.
