Abstract
Compounds of the formula <FORM:1120354/C2/1> wherein R1 is hydrogen, an alkyl, phenylcycloalkyl or cycloalkyl radical, which may be halogen-substituted, containing up to 12 carbon atoms, or an aryl radical, which may be alkyl- or halogen-substituted, containing up to 10 carbon atoms; R2 is an alkyl or cycloalkyl radical, which may be halogen-substituted, containing up to 10 carbon atoms, or R1 and R2 taken together with the central carbon atom may form a cycloaliphatic ring; R3 is an alkyl, cycloalkyl, aryl or aralkyl group which may be alkyl- or halogen-substituted containing up to 10 carbon atoms; R4 is an alkyl or a tert.-aralkyl radical, which may be alkyl- or halogen-substituted, containing up to 10 carbon atoms, or the grouping <FORM:1120354/C2/2> and R2 may also be a radical of formula <FORM:1120354/C2/3> wherein R5 is an alkylene, cycloalkylene, alkenylene, alkinylene or arylene radical containing up to 10 carbon atoms, and R4, only when R2 is not a radical of the above Formula III, may be a group of the general formula <FORM:1120354/C2/4> wherein R7 is the same as R4, and R6 is an alkylene, cycloalkylene, alkenylene, alkinylene or arylene group, which may be alkyl- or halogen-substituted, containing up to 10 carbon atoms, are obtained by reacting, at a temperature of from -30 DEG C. to 80 DEG C., hydrogen peroxide, a monohydroperoxide of the general formula R4-OOH or a di-hydroperoxide of the formula <FORM:1120354/C2/5> with an alkylvinyl ether or an alkylalkenyl ether of the formula <FORM:1120354/C2/6> where R21 is a vinyl or alkenyl radical corresponding to group R2 defined above without one hydrogen atom, in an amount from the chemical equivalent to an excess of 10:1 using as a catalyst a substance whose dispersion in water shows a pH between 3 and 7, which catalyst is a channel type carbon black, an active carbon black, activated alumina, silica gel, a cationexchange resin or activated natural earth. The catalyst is suitably employed in an amount from 0.001 to 100 parts by weight per 100 parts of the reactants and the reaction may be effected in an inert solvent.
