Wittig reagents, as specific enol equivalent

Conjugated Wittig reagents as specific enol equivalents... 

When the Wittig reaction was introduced (Chapter 14) we saw it simply as an alkene synthesis. Now if we look at one group of Wittig reagents, those derived from a-halo-carbonyl compounds, we can see that they behave as specific enol equivalents in making unsaturated carbonyl compounds. 

We have already met one series of specific enol equivalents as Wittig reagents (66) may be used in this way (see Chapter 15).
