Let’s learn more about this compound (cas:1265884-98-7).
A copper-catalyzed conjugate silylation of various cyclobutenone derivatives with Me2PhSiZnCl · 2LiCl or (Me2PhSi)2Zn · xLiCl (x≤4) to generate β-silylated cyclobutanones is reported. Trapping the intermediate enolate with ClP(O)(OPh)2 affords silylated enol phosphates that can be further engaged in Kumada cross-coupling reactions to yield silylated cyclobutene derivatives
