Tm. Greene et al., A MATRIX-ISOLATION AND DENSITY-FUNCTIONAL THEORY STUDY OF THE REACTIONS OF LASER-ABLATED BERYLLIUM, MAGNESIUM, AND CALCIUM ATOMS WITH METHANE, Journal of the American Chemical Society, 120(24), 1998, pp. 6097-6104
Beryllium atoms produced by laser ablation have been co-condensed with
methane/argon mixtures onto a substrate at 10 K. Infrared spectroscop
y has been used to identify a number of organoberyllium products, viz.
CH3BeH, CH3BeCH3, CH3Be, H2CBeH, and HCBeH. Assignments of the infrar
ed absorption bands are made on the basis of H-2 and C-13 substitution
and by comparison with frequencies supplied by DFT calculations. In t
he reaction of magnesium or calcium atoms with methane, the only inser
tion product that could be identified was the monomethyl metal hydride
, CH3MH (M = Mg or Ca).
