✦ Synopsis

A ferrocenylphosphine-silver-isocyanoacetate complex was investigated as a model compound for catalytic species in gold-catalyzed aldol reaction. 'H{lH} NOE studies of the silver complex indicated that terminal amino group of pendant side chain of the ferrocenylphosphine ligand is located close to active hydrogens of isocyanoacetate coordinated.
