Article Synopsis
- Phosphorus-centered disbiradicals, previously unknown, were successfully created by linking two monoradical phosphorus centers through a specific linker.
- The process involved transforming biradical [⋅P(μ-NTer)P⋅] with 1,6-dibromohexane and reducing it with KC, resulting in a disbiradical with nearly 100% biradical character.
- EPR spectroscopy showed unexpected exchange interactions and revealed that the two radical sites have flexible distances in solution, demonstrating the compound’s potential for small molecule activation.
Phosphaalumenes are the heavier isoelectronic analogs of alkynes and have eluded facile synthesis until recently. We have reported that the combination of a phosphinidene transfer agent, TerP(PMe ) ( Ter=2,6-Ar -C H ), with (Cp*Al) (Cp*=C (CH ) ) afforded the phosphaalumenes TerPAlCp* as isolable, violet, thermally stable compounds. In here we describe attempts to utilize Mes*P(PMe ) (Mes*=2,4,6-tBu -C H ) as a phosphinidene source in combination with different Al(I) precursors, namely NacnacAl ( Nacnac=HC[C(Me)NDip] , Dip=2,6-iPr -C H ), (Cp*Al) and Cp Al (Cp =1,2,4-tBu -C H ).
