The current depletion of available primary phosphorus resources is extremely worrying, which is why phosphate rock and elemental phosphorus are listed as critical raw materials worldwide. So far, the value chain from phosphate ores to basic chemicals does not correspond to the guiding principle of "green chemistry". In addition, the problem of phosphorus recovery through suitable large-scale recycling processes to recover valuable phosphorus compounds will become drastically more acute in the future. For these reasons, the development of new and innovative chemical methods in the value chain of the important element phosphorus is urgently needed. In our blueprint for a modern sustainable phosphorus chemistry, we investigate systematic as well as atom and energy efficient ways to either directly convert P4 via our concept of “oxidative onioation“ selectively into salts of versatile P(III) transfer reagents suitable for subsequent formation of P–O, P–N and P–C bonds or the deoxygenation of phosphoric acid and recycled phosphate resources to P1 building blocks,[1] allowing "redox neutral" synthesis of a variety of valuable P(V) compounds. Both concepts represent versatile and chlorine-free approaches to value-added and highly relevant phosphorus containing chemicals.
