| By reaction with surface chromium(II) on silicagel at T > 150 °C, cycloolefins can undergo ring contraction, methylation/demethylation, hydrogenation/dehydrogenation, and iso-meri7ation. Furthermore, n-alkanes (Ci... C4) are formed incorporating support hydrogen. -As in the case of the corresponding acyclic olefins, a common intermediate MC3 (metalla-cyclobutane^HM-allyl complex) for all these reactions is postulated; the transfer of Ci units is claimed to proceed via a carbene M = CH2 derived from the MC3 precursor. | | | |
