Single-pot ozonolytic synthesis of acylhydrazones based on ozonolytic cleavage of 1-methyl-2,2-dichloro-1-ethenylcyclopropane in methanol and the treatment of intermediate peroxides with a twofold excess of hydrazides of a series of carboxylic acids

Cycloalkanes have a closed circuit of the saturated main chain, while in alkanes there is an open-chain or acyclic main chain. Cycloalkanes might have one or more susbtituents groups attached to their rings. Single substituted alkanes are named with

The internal rotation about the single bond connecting a cyclopropyl ring to a CH3, SiH3, GeH3, NH2, SH, or OH group was investigated. Both CCSD/cc-pVTZ and MP2/cc-pVTZ ab initio calculations were performed to predict the structures of these molecule

n-Butane-1-13C is isomerized by “HF-SbF5” to n-butane-2-13C without intermediate or concurrent isomerization to isobutane. The rate of the13C-scrambling reaction is only slightly lower than that of the isomerization of n-pentane to isopentane. Th

The gas-phase thermal decomposition of cis-2-methylcyclopropane carboxylic acid was investigated in the temperature range 692–753 K and pressure between 10 and 70 Torr. Arrhenius parameters were determined for homogeneous, unimolecular formation of
