Transition metal-catalyzed P(O)–H alkenylation, allenylation and alkynylation reactions: A recent trend

Phosphorus-containing unsaturated hydrocarbons, including alkenyl, allenyl, and alkynyl phosphoryl compounds, constitute a significant subclass of organophosphorus intermediates that have extensive applications in organic synthesis and related fields. Among various synthetic approaches, the transition metal-mediated reactions of the readily accessible hydrogen phosphoryl chemicals with alkynes stand out as one of the most efficient and straightforward methods for their preparation. Here, we summarize the recent advancement in transition metal-catalyzed P(O)–H alkenylation, allenylation, and alkynylation reactions to reflect a current research trend of the field.
