EFFECT OF STERIC FACTORS ON THE EQUILIBRIUM IN THE FORMATION OF TERT-BUTYLPEROXY KETALS FROM ALIPHATIC KETONES

The equilibrium in the formation of tert-butylperoxy ketals from aliphatic ketones and tert-butyl hydroperoxide is determined by the steric factors of the substituents at the carbonyl group of the ketones.The dependence of the equilibrium constant on the steric parameters of the substituents is described by the Taft equation log K/KO = δΣEs0 with δ = 1.37 (r = 0.970).

STRUCTURE OF PRODUCTS FROM REACTION OF tert-BUTYL HYDROPEROXIDE WITH SULFURYL CHLORIDE

In the reaction of tert-butyl hydroperoxide with sulfuryl chloride 2,2-bis(tert-butylperoxy)propane and 2-methoxy-2-(tert-butylperoxy)propane were obtained.Certain known physicochemical characteristics were defined more precisely and additional physicochemical characteristics which unambiguously established the structure were investigated.
