On the Relation Between Isomerization Modes for Idealized and Distorted Skeleta

Permutational isomerization reactions [1][2] may occur in two extreme situations. If the n ligands do not distort the symmetry of the skeleton, then the permutations of the full permutation group S n have to be classified [1,3] according to the symmetry group G of the idealized skeleton. If the ligands are sufficiently different, they will be blocked and will distort the skeletal framework. In this case, the allowed permutations belong to S′ n ,...
