1-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. | [Preparation]
The 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).
| [Purification Methods]
Add Et2O, wash with cold H2O, dry (Na2SO4), filter, evaporate Et2O, and distil the oily residue in a vacuum. [Ainsworth et al. J Organometal Chem 46 59 1972.] |
