The Front Cover shows the various “flavours” of α-functionalized phosphine chalcogenides that can be generated from the hydrophosphorylation of C=O/N bonds. Even with multiple potential operative mechanisms such as a concerted [2+2] hydrophosphorylation, or a stepwise P(V)−P(III) tautomerization and subsequent nucleophilic attack, the resultant α-functionalized phosphine chalcogenide remains the same. Additionally, the separation and organization of each α-functionalized phosphine chalcogenide displays that each is distinctly unique and is treated as such throughout the course of the Review. More information can be found in the Review by J.-W. Lamberink-Ilupeju, P. J. Ragogna, and J. M. Blacquiere.
