A stable
dialkylphosphinyl radical, 2,2,5,5-tatrakis(trimethylsilyl)-1-phosphacyclopentan-1-yl (RH2P•), showed both irreversible one-electron oxidation
and reduction peaks at −0.24 and −2.29 V vs ferrocene/ferrocenium
couple. One-electron reduction of RH2P• with KC8 in the presence of 18-crown-6 (18-c-6) or [2.2.2]cryptand
(crypt-222) gave the corresponding phosphides [K(18-c-6)]+[RH2P]− and [K(crypt-222)]+[RH2P]−. Whereas [K(18-c-6)]+[RH2P]− exists as
a contact ion pair, [K(crypt-222)]+[RH2P]− exists as a solvent-separated ion pair in the
solid state. Reaction of RH2P• with AgOTf afforded an unexpected product, a silver(I) phosphaalkene
complex.
