Acyl peroxides mixed

Sym. acyl peroxides. Ethereal HgOg-soln. added at -15° to a soln. of phenyl-propiolic chloride in abs. ether, then pyridine added dropwise with stirring, which is continued 2 hrs. diphenylpropiolyl peroxide (Caution, explosive). Y 74.5%. C. Bischoff and K.-H. Platz, J. pr. 312, 2 (1970) also mixed acyl peroxides s. Do Linh Khuong, G. S. Bylina, and Y. A. OPdekop, Akad. Navuk Belarus. SSR, Ser. Khim.

Thermal decomposition in three different ways, i.e. homolytic, polar and radical induced decomposition, as well as intermolecular reaction of sulfonyl peroxides are the main reactions displayed by sulfonyl peroxides. When bis(arylsulfonyl) peroxides are allowed to decompose at 25-40 °C in chloroform, homolytic 0—0 bond fission followed by hydrogen abstraction from the solvent results in the formation of the corresponding arylsnlfonic acids. Mixed acyl sulfonyl peroxides undergo complicated thermal decomposition in solution, and have been used commercially as polymerization initiators, since they provide a source of free radicals at a relatively low temperature . 

Peroxy acids. Konen and Silbert have developed a mild, general synthesis of peroxy acids entailing first acylation of silver diethyl phosphate in ether solution followed by perhydrolysis of the mixed anhydride with hydrogen peroxide (98%... 

Acyl phosphonates behave similarly to a-diketones towards hydrogen peroxide, affording mixed anhydrides. ...
