of the hydrophosphorylation reaction can be controlled by varying the catalyst loading. A flexible one‐pot access to vinylmonophosphonates and alkylbisphosphonates was demonstrated using simple starting materials in an atom‐economic reaction without any specific solvents or ligands. Monitoring of the reaction mechanism with joint NMR and MS studiesrevealed key information about the reaction intermediates
