The condition of stability obtained earlier is generalized for the case of arbitrary force-free fields (f.f.f.). It is shown that the configurations are stable, if the ratio of the current to the field and its gradient are small enough.
The bisketenes 2-phenyl and 2-methyl-3-(trimethylsilyl)-1,3-butadiene-l,4dione (8 and 10) are calculated on the basis o f additivity of substituent effects to be less stable than the 3-phenyl and 3-methyl-4-(trimethylsilyI)cyclobut-3-ene-l,2-diones (7 and 9) by 1.9 and 2.6 kcal/mol, respectively. In
