    • The present invention includes polymerization catalyst activator complexes which include at least Group 13 metals. The activator complexes of the invention are prepared, in general, by reacting a halogenated aryl Group 13 metal compound with a diol. The activator compound is represented in one aspect by: wherein each M1 is a Group 13 atom; each R3, R3′, R3″, and R3′″ group is independently selected from, for example, C1 to C30 alkyls, halogenated C1 to C30 alkyls, C6 to C60 halogenated aryls; with the proviso that at least one of R3, R3′, R3″, and R3′″ is a fluorinated C6 to C60 aryl group; R1 and R2 are independently selected from substituted or unsubstituted C1 to C100 hydrocarbylenes; R, when present, is a substituted or unsubstituted C30 hydrocarbylene; wherein when R is absent, R1 and R2 are bound together; and x is 0 or an integer from 1 to 100.

    • A promoter can have utility in selective heterogeneous oxidation of arylalkyl hydrocarbons such as, for example, cyclohexyl benzene and/or sec-butyl benzene to form hydroperoxides. The promoter can include the product of contacting a solid support comprising a metal oxide surface and an iron compound. The solid support can include, for example, titanium dioxide and/or an iron oxide such as magnetite and can have magnetic susceptibility. A method for the oxidation of arylalkyl hydrocarbons to form hydroperoxides can include contacting 16 an arylalkyl hydrocarbon with oxygen in the presence of the promoter under catalytic oxidation conditions to form arylalkyl hydroperoxide, which can then be converted to phenol via cleavage 26. The method can include recovery 22 of the promoter from the arylalkyl hydroperoxide and can further include recycling the recovered promoter to the contacting 16. Where the solid support has magnetic susceptibility, the recovery 22 can include magnetic separation of the promoter.
    • 助催化剂可用于芳基烷基烃例如环己基苯和/或仲丁基苯的选择性异相氧化以形成氢过氧化物。 助催化剂可以包括使包含金属氧化物表面和铁化合物的固体载体接触的产物。 固体支持体可以包括例如二氧化钛和/或氧化铁如磁铁矿,并且可以具有磁化率。 用于氧化芳基烷基烃以形成氢过氧化物的方法可以包括在催化氧化条件下在助催化剂存在下使芳烷基烃与氧接触,形成芳基烷基氢过氧化物,然后可通过裂解将其转化为苯酚。该方法可包括 从芳基烷基氢过氧化物中回收22个启动子,并且可以进一步包括将回收的促进剂再循环到接触16.当固体支持物具有磁化率时,回收22可以包括促进剂的磁性分离。
