The last few years have seen an explosive growth in the use of silyl enol ethers and silyl ketene acetals in organic synthesis. The aim of this review is to provide a reasonably comprehensive account of the newer reactions of these compounds, illustrated by some examples from synthetic pathways. 1. Introduction 2.
