Abstract

Results Synthesis and Product Studies. The classical synthetic route to dioxetanes was employed, ie, olefin to P-bromo hydroperoxide (BHP) to di~ xetanes.~ The olefins were prepared from cross-coupling of fluorenone with the acetophenones with low-valent titanium, with one exception. For 3 (Ar= 3, 4-(CH3) 2C6H3 and p-BrC6H4), the McMurry procedure was used, where titanium trichloride was reduced with lithi~ m.~ With one ...
