✦ Synopsis

E&r since It was disrxvemd that both slrglet, and triplet states of allphatic ketones participate in Type II photoeliminat.icn processes (11, there has been speculation abmt the relative reactlvlties of the two excited states. In the cwl&lal report of polar solvent effects on photoelimination (2), one experiment was described which Indicated that ~-butyl alcohol enhances the quantunefficiency ofailythetrlpliztstateof 2-octanone.
