Unprecedented Formation of μ-Vinylidene Complexes from Phospharuthenocene and Acyl Chloride via Activation of the C═O Double Bond
摘要:
A novel reaction mode of phosphametallocenes was discovered. The phospharuthenocenes with cyclohexyl substituents at the alpha-positions of the eta(5)-phospholide(s) reacted with acyl electrophiles by an initial electrophilic attack to the ruthenium to produce the mu-alkenylidene species with activation of the acyl C=O double bond and elimination of an alpha-hydrogen.
