Small Rings, 42. Attempts to Prepare Oxirenes via Photochemical Cycloreversions
Photochemically induced cycloreversions, which are ideally suited for the matrix isolation of cyclobutadienes, cannot be used for an analogous preparation and identification of oxirenes.In some cases ketenes are formed instead.

Small Rings, 41. Oxirene: Intermediate or Transition State? Matrix Irradiation of Diazoketones
On irradiation of diazoketones - even of those which do not undergo a Wolff rearrangement under standard conditions - in an argon matrix at 10 K oxirenes (or acylcarbenes) cannot be detected directly.
