1.
ESR and spin-trap methods have been used to show that the interaction of Fe(CO)5 or Fe(C5H5)2 with peroxides leads to the formation of acyloxy radicals. Carried out in CCl4, these reactions lead to the formation of both acyloxy and.CC13 radicals. Initiated by the Fe(CO)5 or Fe(C5H5)2+benzoyl peroxide systems, the reaction of BrCCl3 with α-olefins lead to the formation of.CCl3 radicals and adducts of these radicals with the olefin: CCl3CH2 .CHR1, where R1=C4H9, C6H13. Initiated by the iron compound + acyl peroxide system, tetrahalomethane addition to olefins proceeds through a radical chain mechanism, chain propagation being through the.CCl3 radicals.

2.
Spin adducts of α-phenyl-N-tert-butylnitron with acyloxy and.CCl3 radicals, and 2-methyl-2-nitrosopropane with.CCl3 and CCl3CH2CHR (R is an alkyl) radicals, have been identified.
