description Basic Metals. II. Protonation and Alkylation Reactions of π‐Cyclopentadienyl‐metal‐bis(tert.‐phosphite) Complexes Für «Basische Metalle. I» siehe [1]. The complexes C5H5Co[P(OR)3]2 (R = CH3, C2H5) and C5H5Rh[P(OR)3]2 (R = CH3, C2H5, C6H5, C6H4‐o‐CH3) react with electrophilic agents E+, e.g. H+ and CH3+, to give [C5H5ME(P(OR)3)2]+. Salts of these cation have been isolated with BF4− and PF6− as the anions. The formation of compounds with direct M‐H and M‐CH3 bonds points to the pronounced Lewis‐base properties of the metal atom in the starting complexes. The NMR. data of the cations [C5H5MH(P(OR)3)2]+ and [C5H5MCH3(P(OR)3)2]+ will be discussed.
