Kinetics and mechanism of unimolecular heterolysis of framework compounds: XX. Solvation and steric effects in heterolysis of 2-halo-2-alkyladamantanes in sulfolane and butanol

Hetrolysis rate of 2-halo-2-phenyladamantanes in BuOH is 1000 times higher than the heterolysis rate of 2-halo-2-methyladamantanes. The heterolysis rate in sulfolane does not depend on the substituent, but the phenyl group exhibits a negative steric effect.

Kinetics and mechanism of unimolecular heterolysis of carcass compounds. XV. The nature of solvation effects in heterolysis of 2-bromo-2-phenyladamantane in dipolar aprotic solvents

Heterolysis kinetics of 2-bromo-2-phenyladamantane in MeCN,γ-butyrolactone, sulfolane, and cyclohexanone were studied with verdazyl method. The rate is described by an equation w = k[RBr], and the reaction proceeds by SN1 mechanism. The decreas

REACTION OF 2,4,6-TRIPHENYLVERDAZYL WITH TRIFLUOROMETHYLSULFONYLCARBETHOXYDIBROMOMETHANE

An unusual acylation of 2,4,6-triphenylverdazyl by trifluoromethylsulfonylcarbethoxydibromomethane in benzene has been discovered leading to 1-ethoxalyl-2,4,6-triphenyl-1,2,3,4-tetrahydro-sym-tetrazine (1-ethoxalyl-2,4,6-triphenylleukoverdazyl).
