Wittig reaction retrosynthetic analysis using

Applying retrosynthetic analysis, the presence of the alkene group in the target suggests using a Wittig reaction in its preparation. 

Determine the Starting Materials for a Wittig Reaction Using Retrosynthetic Analysis... 

Synthesize 2-methyl-1-phenylprop-l-ene using a Wittig reaction. Begin by writing a retrosynthetic analysis. 

Wittig reactions, and reactions related to it, are used for the regiospecific synthesis of alkenes from aldehydes and ketones. Their retrosynthetic analysis begins with disconnecting the double bond as shown and introduces a novel stmctural type called an yiide.
