An Alkali Amide Approach to Triphosphabenzenes

Angewandte Chemie International Edition, EarlyView.
Alkali metal amides offer a simple route to phosphorus aromatics. LiNMe2 catalyzes [2+2+2] cyclotrimerization of a phosphaalkyne, while tetrahydrofuran (THF) stabilizes a λ4‐triphosphabenzene anion intermediate. Using KN(SiMe3)2 switches reactivity to arene C(sp3)─H activation, giving benzylated λ4‐triphosphabenzenes and rare λ5‐triphosphabenzenes ...
