Syntheses and Reactions of 3-Phenyloxete and the Parent Unsubstituted Oxete
Friedrich, Louis E.,Lam, Patrick Yuk-Sun
, p. 306 - 311 (2007/10/02)
The elimination of p-toluenesulfonic acid and o-nitrophenylselenilic acid from substituted oxetanes gives 3-phenyloxete (6) and oxete (9), respectively. 3-Phenyloxete (6) undergoes the expected chemistry as well as a facile addition of triplet oxygen to g
