摘要: The stereochemistry of the olefin metathesis has been subject numerous publications which tried to rationalize behaviour various catalysts with acyclic olefins [1-5]. It had noticed during these studies that a cis gave preferentially and trans led essentially olefin. This was explained in terms stability metallacyclobutanes involved catalytic cycle (Scheme 1): most favoured are those where substituents positions 1 3 equatorial. simple rule allowed explanation experimental results configuration retention.
