| Abstract: | All reported attempts to synthesize the tert‐butyl‐substituted adamantoid phosph(III)azane P4(NtBu)6 have failed, leading to the classification of this molecule as inaccessible and a literature example of steric control in chemistry of phosphorus‐nitrogen compounds. We now demonstrate that this structure is readily accessible by a solvent‐free mechanochemical milling approach, highlighting the importance of mechanochemical reaction environments in evaluating chemical reactivity. |
