Terf-butyl perbenzoate

In addition to the symmetrical peroxides, asymmetrical peroxides are also in use, as for example, terf-butyl perbenzoate, terf-butylcumyl peroxide, and some polymeric peroxides [47]. 

Catalytic amounts of this addend (4 equiv relative to Cu) increase the selectivity of the allylic oxidation when TBHP is used as the oxidant. No change was observed with terf-butyl perbenzoate. This observation suggests a dichotomy in the mechanism of this reaction when using the two oxidants. Furthermore, in the absence of anthraquinone, a small negative nonlinear effect (78) is observed while in its presence, a small positive nonlinear effect appears. The reasons for this reversal are not clear, although the authors observed that low enantiopurity catalysts lead to turbid... 

Some fabrication processes, such as continuous panel processes, are run at elevated temperatures to improve productivity. Dual-catalyst systems are commonly used to initiate a controlled rapid gel and then a fast cure to complete the cross-linking reaction. Cumene hydroperoxide initiated at 50°C with benzyl trimethylammonium hydroxide and copper naphthenate in combination with tert-butyl octoate are preferred for panel products. Other heat-initiated catalysts, such as lauroyl peroxide and terf-butyl perbenzoate, are optional systems. For higher temperature molding processes such as pultmsion or matched metal die molding at temperatures of 150°C, dual-catalyst systems are usually employed based on erf-butyl perbenzoate and 2,5-dimethyl-2,5-di-2-ethylhexanoylperoxy-hexane (Table 6). 

Recently, free-radical homopolymerizations and copolymerizations of styrene were performed in toluene and iV,N-dimethylformamide (DMF) as solvents in the presence of different initiators (i.e., tert-butyl perbenzoate (tBPB), dibenzoyl peroxide (DBPO), di-terf-peroxide (DtBP), dicumyl peroxide (DCP), and lauryl peroxide (LP) (Figure 7)). ...
