Anwendungen · 1 Eintrag

Verwenden1-Methoxy-2-methyl-1-(trimethylsilyloxy) propene is widely used as functional equivalent of enolate of methyl isobutyrate; ester enolate surrogate in electrophilic reactions including alkylation, aldol reaction, Michael reaction, initiator for group transfer polymerization of acrylates, nitroarylation, oxidation, dimerization, and cycloadditions.

Darstellung · 1 Eintrag

synthetischeThe title compound is a prototypical ketene silyl acetal (KSA) that can been prepared by either of the two most commonly employed methods: (a) deprotonation of the |á-hydrogen of an ester followed by silylation (1),16 and (b) metal-catalyzed hydrosilylation of |á,|-unsaturated esters(2).
