Notizen:
The dipole moments of 2,3-benztropone (11), 4,5-benztropone (III) and of 2,7 dialkyl-substituted 4,5-benztropones have been determined. The difference in dipole moment between II and III can be attributed to differences in geometry, rather than to varying amounts of polar character. Attention is drawn to the exceptional dipole contribution of alkyl gronps in 2,7 -dimethyl-4,5-benztropone and 2,7 -do deca- methglene-4,5-beuztropone (VIII). Dipole as well as molecular refraction data confirm conclusions drawn in previous publications about the relative geometries of VIII and of 2,7-pentamethylene-4,5-benztropone.
