, p. 507 - 510 (1992)
The kinetic resolution of 1-methyl-1-phenylpropyl hydroperoxide via catalytic Sharpless epoxidation with various allylic alcohols has been investigated. An enantiomeric excess of nearly 20% of the resolved hydroperoxide has been observed.

Page/Page column 6-7, (2011/05/03)
In a process for producing alkylbenzene hydroperoxides, a feed comprising (i) sec-butylbenzene, (ii) cumene in an amount greater than 10 wt % of the total feed and (iii) at least one of iso-butylbenzene and tert-butylbenzene in an amount up to 20 wt % of the total feed is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I): wherein each of R1 and R2 is independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SO3H, NH2, OH, and NO2 or from the atoms H, F, Cl, Br, and I, provided that R1 and R2 can be linked to one another via a covalent bond; each of Q1 and Q2 is independently selected from C, CH, N and CR3; each of X and Z is independently selected from C, S, CH2, N, P and elements of Group 4 of the Periodic Table; Y is O or OH; k is 0, 1, or 2; l is 0, 1, or 2; m is 1 to 3; and R3 can be any of the entities listed for R1. The contacting is conducted under conditions to convert the sec-butylbenzene and cumene to their associated hydroperoxides.
PROCESS FOR PRODUCING PHENOL

Page/Page column 20-21, (2010/04/28)
In a process for producing phenol or a substituted phenol, an alkylaromatic hydroperoxide having a general formula (I): R1 / (I) I2C R2 in which R1 and R2 each independently represents an alkyl group having from 1 to 4 carbon atoms, provided that R1 and R2 may be joined to form a cyclic group having from 4 to 10 carbon atoms, said cyclic group being optionally substituted, and R3 represents hydrogen, one or more alkyl groups having from 1 to 4 carbon atoms or a cyclohexyl group, is contacted with a catalyst comprising an oxide of at least one metal from Groups 3 to 5 and Groups 7 to 14 of the Periodic Table of the Elements and an oxide of at least one metal from Group 6 of the Periodic Table of the Elements.
