Reactions of Frustrated Lewis Pairs with Chloro-Diazirines: Cleavage of N=N Double Bonds.

ABSTRACT: The reactions of FLPs with diazomethanes leads to the rapid loss of N₂ . In contrast, in this work, we reported reactions of phosphine/borane FLPs with chlorodiazirines which led to the reduction of the N=N double bond, affording linked phosphinimide/amidoborate zwitterions of the general form R₃ PNC(Ar)NR'BX(C₆ F₅ )₂ . A detailed DFT mechanistic study showed that these reactions proceed via FLP addition to the N=N bond, followed by subsequent group transfer reactions to nitrogen and capture of the halide anion.
