Abstract
Abstract:
For the first time, a sonochemical method has been developed for the structural rearrangement of
[5,6]-open mono- and poly adducts of fullerene C60 containing spirocyclic fragments of camphor analogs into
[6,6]-closed isomers. The isomerization reaction occurs with quantitative yield under mild conditions: 1 hour at
room temperature. A probable mechanism of sonochemical isomerization has been proposed. Mono- and poly
adducts of C60 fullerene containing spirocyclic fragments of camphor analogues were obtained in the reaction
of metal complex catalysis by the Pd(acac)2–2PPh3–4Et3Al system with the participation of fullerene and diazo
compounds.
