Rev., 56, 219 (1956); Org. React., 9, 341 (1957). For the mercury(II) oxide method, see: Org. Synth. Coll., 5, 126 (1955); 6, 179 (1988):
  • Literature references should be checked to see whether the red form or the more finely-divided yellow form of the oxide is specified, although this may not be stated.
