Conclusions
-
1.
The carbonyl group of benzoylcyclopropanes containing a chlorinated three-membered ring is rotated out of the bisector plane by an angle of 30–40°; in the presence of cis substitutents the direction of this rotation is such as to increase the distance between these substituents and the carbonyl hydrogen.
-
2.
The phenyl radicals are rotated by an angle of 15–40° with respect to the carbonyl plane, the direction of rotation being such as to increase the distance between the most closely neighboring hydrogen atoms.
