The Müller and Riedel group reveal the structure of protonated white phosphorus in solution!

News vom 04.10.2018

Even though the chemistry of P4 has been investigated for many decades, its chemical reactivity towards the simplest electrophile, the proton, is still virtually unknown. The Müller and Riedel group report now for the first time on the successful protonation of P4 by the Brønsted superacid H[Al(OTeF5)4](solv). The spectroscopic results are in agreement with an acid-mediated activation of P4 under protonation of an edge of the P4-tetrahedron and formation of a three-center two-electron P–H–P bond. These investigations are of fundamental interest as they permit the activation of P4 with the simplest electrophile as a new prototype reaction for this molecule.
