Аннотация:2-Ferrocenylmethylidene-3-methyl-1-azoniabicyclo[2,2,2]octane-3-cation and 2-ferrocenylmethylidene-1,2,7,7-tetramethylbicyclo[2,2,1 ]heptane-2-cation tetrafluoroborates and tetraphenylborates having bulky substituents in their molecules have been found to isomerise in solutions with inversion of configuration at the double bond, Tetrafluoroborates and tetraphenylborates of the 3-methyl-2,3-(1-piperidinium-1,4-diyl)-l-ferrocenylallyl cation and the 3-methyl-2,3-(1,2,2-trimethylcyclopentane-1,3-diyl)l-ferrocenylallyl cation with bulky substituents at the C1( )atom isomerise in solutions with inversion of configuration at the C-1-C-2 bond.
