The present invention relates to a new class of peroxides and to a process for the preparation of these peroxides having the general formula (I),
wherein n=1 or 2, R1, R2, R4, R5, and R6 are independently selected from the group comprising hydrogen, C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C7-C20 aralkyl, and C7-C20 alkaryl, or R1 and R2 form a C3-C12 cycloalkyl group, which groups may include linear or branched alkyl moieties; and each of R1, R2, R4, R5, and R6 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, and R1 and R2 may form a ring, and
R3 is independently selected from the group comprising C1-C20, alkyl; C3-C20 cycloalkyl, C6-C20 aryl, C7-C20, aralkyl, and C7-C20 alkaryl, which groups may include linear or branched alkyl moieties; and R3 may optionally be substituted with one or more groups selected from hydroxy, alkoxy, linear or branched alkyl, aryloxy, halogen, ester, carboxy, nitrile, and amido, and any pair of the optionally substituted R3, R4, R5, and R6 may form a ring, comprising the reaction of the corresponding ketone.
本发明涉及一种新型过氧化物及其制备方法,其具有一般式(I),其中n=1或2,R1、R2、R4、R5和R6独立地选自氢、C1-C20烷基、C3-C20环烷基、C6-C20芳基、C7-C20芳基烷基和C7-C20烷基芳基,或者R1和R2形成C3-C12环烷基,其中这些基团可以包括线性或支链烷基;R1、R2、R4、R5和R6中的每一个可以选择性地被一个或多个羟基、烷氧基、线性或支链烷基、芳氧基、卤素、酯基、羧基、腈基和酰胺基中的一个或多个基团取代,且R1和R2可以形成一个环;R3独立地选自C1-C20烷基、C3-C20环烷基、C6-C20芳基、C7-C20芳基烷基和C7-C20烷基芳基,其中这些基团可以包括线性或支链烷基;R3可以选择性地被一个或多个羟基、烷氧基、线性或支链烷基、芳氧基、卤素、酯基、羧基、腈基和酰胺基中的一个或多个基团取代,任意一对选择性取代的R3、R4、R5和R6可以形成一个环,包括对应酮的反应。
