Allylic phosphorus ylides are a class of important and versatile intermediates in synthetic organic chemistry. Due to the delocalization of the carbanion center, an array of vinylogous organic reactions of allylic phosphorus ylides throughγ-attack of the carbanion have been achieved in recent years. This mini-review aims to summarize the vinylogous reactivity of allylic phosphorus ylides toward carbonyl compounds, mainly including vinylogous Wittig reactions and various annulation reactions. These reactions broaden the application of allylic phosphorus ylides in organic chemistry, and also provide new synthetic methods for many important organic molecules.
