Abstract

Reaction of methylmagnesium iodide and 3-bromotropolone(Ia) yielded colorless plates (Ila) whose ultraviolet spectrum was similar to that of troponez)(Fig. 1), suggesting that it is monobromo-2-methyltropone. As 3-bromotropolone is in a" high mobile tautomeric" system as represented with A and A', two isomeric monobromo-2-methyltropone, ie 7-bromo-2- methyltropone (B) and 3-bromo-2-methyltropone (B') should be obtained by this reaction. ...
