Geminated adsorbed cycloalkanes

Geminated adsorbed cycloalkanes, 30 62-63 Generalized valence bond technique, 34 138... 

Stability of geminated adsorbed cycloalkanes by replacing the metallocyclobutane in Scheme 72 by a species attached to two metal atoms (Scheme 73). Indeed, 1,3-dicarbenes are likely to be more stable than 1,2-cyclic dicarbenes, and demethylation would then appear as an extension of the Leclercq-Maurel mechanism 82. ... 

The difference in the behavior of geminated and nongeminated adsorbed cycloalkanes was explained by assuming that in the former case, multiple attachment of the organic moiety to the metal, required for complete degradation to methane, was prevented by steric interactions between the surface and the gemdimethyl group. One could also explain the relative...
