Abstract

The preparation and the absorption spectra of 2‐alkyl‐ and 2,7‐dialkyl‐4,5‐benztropones (with alkyl = methyl, ethyl, propyl, hexyl, iso‐propyl and tert.‐butyl), and of 5,7‐dialkyl‐2,3‐benztropones (with alkyl = methyl and ethyl) are described.

## Abstract 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. Att
