We report the synthesis of new Lewis-acidic boranes tethered to redox-active vanadium centers, (Ph2N)(3)V(mu-N)B(C6F5)(2) (1a) and (N(CH2CH2N(C6F5))(3))V(mu-N)B(C6F5)(2) (1b). Redox control of the V-IV/V couple resulted in switchable borane versus "hidden" boron radical reactivity, mimicking frustrated Lewis versus frustrated radical pair (FLP/FRP) chemistry, respectively. Whereas heterolytic FLP-type addition reactions were observed with the V-V complex (1b) in the presence of a bulky phosphine, homolytic peroxide, or Sn-hydride bond cleavage reactions were observed with the V-IV Rcomplex, [CoCp2*](N(CH2CH2N(C6F5))(3))V(mu-N)B(C6F5)(2)] (3b), indicative of boron radical anion character. The extent of radical character was probed by spectroscopic and computational means. Together, these results demonstrate that control of the V-IV/V oxidation states allows these compounds to access reactivity observed in both FLP and FRP chemistry.
