Abstract
A super active catalyst (T.F. = 0.2 ∼ 0.3) for alkene metathesis reaction was prepared by coordinating CH2 radicals onto sublimed molybdenum oxide films, where the radicals were prepared by the reaction of CH2I2 with Al or Mg metals deposited near the oxide film.

Generation of ethane was observed on CH3I/Mg, but not on CH3I/Al, that is, Mg is preferable to Al for the formation of CH3 radical.
A slight activation after the treatment with CH3I in fig. 1 and table 1 is comparable to the activation observed on the blank test by Al or Mg metal deposition (run 2).
