Abstract
The structure and stereochemistry of 2-bromo-4-[2-bromo-(E)-propylidene]-6-methoxy-2,5-cyclohexadien -1-one, C 10 H 10 Br 2 O 2 (1), has been elucidated by X-ray crystallographic analysis. In chloroform or benzene solution, (1) underwent partial isomerization to 2-bromo-4-[2-bromo-(Z)-propylidene]-6-methoxy-2,5-cyclohexadien-1-one, (2). NMR data for (1) and (2) are reported. The crystal investigated (at 173 K) contained 94% of (1) and 6% of (2) (solid solution).
