- Gas-phase addition of [13C]methylene to ethene: Rearrangement of chemically excited propene
-
Reaction of ethene with singlet [13C]methylene, generated photochemically from [13C]diazomethane at four pressures in the range 35-800 Torr, reveals rearrangement of excited [3-13C]propene (3), the product of insertion, to [1-13C]propene (1) and [2-13C]propene (2). This previously unrecognized reaction is formulated as the reverse of the thermal rearrangement of cyclopropane to propene, well known in both thermal and chemically excited modes. The origin of a small excess of 1 over 2 is discussed. Mercury sensitization does not alter the observations at 820 Torr.

- The Formation of Acetone Complexes from the Reaction of CO with 2(μ-O) (Y=Me, Cl) and their Decomposition Reactions
-
The reaction of 2(μ-O) (Y=Me, Cl) and CO gives η2-acetone complexes, which liberate Me2CO upon treatment with oxygen and Me2CHOH upon hydrolysis, and their thermal decomposition proceeds with deoxygenation of the acetone ligand an
