## Abstract Acid‐catalysed decomposition of tropyl ether gives tropone and cycloheptatriene in 83.5 and 90 % yields, respectively. Chlorination of tropone in carbon tetrachloride solution yields tropone dichloride, which can be made to isomerize to the hydrochloride of 2‐chlorotropone; 2‐chlorotro
## Abstract Interaction of tropone and phenylmagnesium bromide yields 2‐phenyl‐2,7‐dihydrotropone (II). This compound is in thermal equilibrium with 2‐phenyl‐6,7‐dihydrotropone (III) in a 1: 4 ratio. The reaction of 2‐chlorotropone with isopropylmagnesium bromide yields a mixture of chloroisopropy
Four distorted tropones with bicyclic bridges were synthesized and their structures and physical properties investigated. They represent most distorted examples of tropone and exhibit abnormalities in various spectra and the decarbonylation reaction.
