Hazard Class | 3 |
{ALF} Silyl ketene acetal. The silyl enol ether of methyl isobutyrate. Catalyst for the initiation of group transfer polymerization, for controlled polymerization of ɑß-unsaturated esters, ketones, nitriles and amides, in which the ketene acetal function is transferred along the growing polymer chain: J. Am. Chem. Soc., 105, 5706 (1983); Science, 222, 39 (1983).
{ALF} Michael additions to enones, catalyzed by Yb(OTf)3, have also been reported: Tetrahedron Lett., 33, 6815 (1992).
{ALF} With imines, gives ß-amino esters or ß-lactams according to conditions: Tetrahedron Lett., 3643 (1977); Chem. Lett., 1397 (1989); Tetrahedron, 44, 4157 (1988).
{ALF} In the presence of a Lewis acid e.g. TiCl4 or TMS-OTf, undergoes the Mukaiyama aldol reaction with aldehydes to give methyl ɑɑ-dimethyl-ß-hydroxy esters: Chem. Lett., 989 (1975); Synth. Commun., 13, 449 (1983). Excellent results are obtained in these reactions with lanthanide triflates, e.g. Yb(OTf)3, as catalysts: Synthesis, 371 (1993).
