Abstract

The effect of sodium dodecyl sulfate (SDS) loading in fluoroboric acid catalyzed Mannich-type reactions of ketene silyl acetals with aldimines was studied. The reaction proceeded smoothly in the presence of 1 mol% of SDS. Formation of small particles was observed by transmission electron microscopy.

We formerly studied the loading of SDS using a ketene silyl enol ether as a substrate.
