bonds of allylarene derivatives were cleaved for reaction with various ketones, affording the homoallylic alcohols in moderate to good yields. The branch/linear selectivity depended on the steric and electronic factors of the ketoneelectrophiles. The intermediate in this reaction is thought to be a low-valent allylcobalt(I) species, which exhibits high nucleophilicity toward ketones.
The present invention relates to novel compounds of the formula 1, their preparation, intermediates for the preparation and the use of the compounds of the formula 1
as catalysts in various metathesis reactions.
The novel metathesis catalysts, which are obtained from readily available precursors, have a high activity and can be used for any type of metathesis reaction.
