| Abstract: | Analytically pure, dark blue pentaphenylborole (PPB) can be synthesized from 1,1-dibutyl-2,3,4,5-tetraphenylstannole and C6H5BCl2 in toluene in 95% yield. Reduction of PPB with elemental potassium in THF produces brownish red K2[PPB] which is derived from the new 6π-electron anion [PPB]2?. The new complexes (C5H5)Co(PPB) and (COD)Pt(PPB) (COD = 1,5-cyclooctadiene) are obtained by irradiation of a toluene solution of (C5H5)Co(CO)2 and PPB and by ligand substitution reaction from Pt(COD)2 and PPB respectively. |
