Реферат:
Biacetyl (butane‐2,3‐dione) adsorbs to silica via H bonding. Splitting of the central C‐C bond occurs on adsorption on Rh particles in Rh/SiO2 catalysts. The resulting surface‐acetyl species seems to undergo rapid decomposition even at temperatures below 300K and leads to the formation of chemisorbed CO and methyl fragments. Based on the principle of microscopic reversibility, it is concluded that acetyl species may be formed under catalytic conditions from chemisorbed CO and methyl species by migratory insertion of CO into the metal‐carbon bond of a chemisorbed methyl fragment.
