Abstract

Ia Ib oxide)(Ia or Ib), namely, those described by (1) Dauben and Ringold, who catalytically hydrogenolyzed 2, 4, 7-tribromotropone, which resulted from the bromination and subsequent heating of 2-cycloheptenone and (2) Doering and Detert, 3 who brominated the product (“rnethoxytropilidene”) obtained by irradiating a mixture of anisole and dia~ omethane.~ Because of tropone's novel position in the field of aromatic chemistry and ...
