Аннотация


Triphenylbismuth dicrotonate Ph3Bi(O2CCH=CHCH3)2 in benzene solution in the presence of 2-methyl-2-nitrosopropane decomposes in light. The phenyl radicals formed as the result of Ph3Bi(O2CCH=CHCH3)2 decomposition are confirmed by the spin-trapping method; they can initiate the methylmethacrylate polymerization at room temperature. In the absence of light the decomposition has not been observed.
