Kinetics of heterolysis of 1-chloro-1-methylcyclopentane in MeOH, BuOH, cyclohexane, i-PrOH, t-BuOH, tert-C5H11OH, γ-butyrolactone, MeCN, PhCN, PhNO2, acetone, PhCOMe, cyclohexanone, and 1,2-dichloroethane at 25-50°C were studied by the verdazyl method. Correlation analysis of solvent effects on activation parameters of the reaction in 8 protic (additionally, AcOH and CF 3CH2OH) and 8 aprotic solvents together and separately in either group of solvents was performed. In all the solvents studied, two ΔH≠-ΔS≠ compensation effects were revealed.

A novel design of electroactive components of rechargeable organic batteries based on stable verdazyl radicals bearing various substituents is proposed. 3-Positioned aromatic substituents at the verdazyl moiety affect the reduction potentials and almost do not affect the oxidation potential, while 1-positioned aromatic substituents affect contrariwise the oxidation potential of this radical without any influence on the reduction potential. The acquired electrochemical data allowed us to reveal the structure—potential relationship for the cathodic and anodic processes, which provided the design of triarylverdazyl radicals possessing record-breaking parameters of the “electrochemical gap”.
Kinetics and mechanism of monomolecular heterolysis of commercial halogenated organic compounds: XXVI. Correlation analysis of solvation effects in dehydrobromination of 1-bromo-1-methylcyclohexane and tert-butyl bromide

The dehydrobromination rate of 1-bromo-1-methylcyclohexane and tert-butyl bromide increases with increasing polarity, electrophilicity, and cohesiveness of a solvent, and decreases with increasing solvent nucleophilicity and polarizability; a negative effect of nucleophilic solvation is observed.
