Intertwined Analytical, Experimental and Theoretical Studies on the Formation and Structure of a Copper Dienolate

The reaction of a silyl dienolate, Cu(II) salt and TBAT yielding the corresponding copper dienolate is addressed. A combined NMR cyclic voltammetry analysis first highlight role in to Cu(I) reduction structure precatalytic species. From these results second set theoretical studies enable determination mechanism formation catalytic Finally, we showed that catalyst promote E/Z s-cis/s-trans equilibration precursor through intermediate. All unveil some peculiarities asymmetric vinylogous Mukaiyama reaction.
