Reactions of alpha-boranophosphorus compounds with electrophiles: alkylation, acylation, and other reactions.

The homologation of phosphorus carbenoids with organoboranes leads to alpha-boranophosphorus compounds, which can be further functionalized through reactions with various electrophiles, either directly or after activation to the corresponding borate. A variety of substituted organophosphorus compounds can be obtained in one pot via reaction with many electrophiles. Complex structures are prepared in a single step using simple building blocks.
