Synthesis, structure and reactivity of new low-valent mono(η-arene)niobium compounds
摘要:
The new compounds [Nb(eta-C6H5Me)(PMe3)3R] (R = H or SiMe3), [Nb(eta-C6H5Me)(tmps)], dagger [Nb(eta-C6H5Me)(tmps)H] [tmps = MeSi(CH2PMe2)3], [Nb(eta-C6H5Me)(eta-C5H5)(PMe3)], [Nb(eta-C6H5Me)(eta-5-C9H7)(PMe3)], [Nb(eta-5-C9H7)(CO)3(PMe3)], dagger [Nb(eta-C7H7)(eta-4-C7H8)(PMe3)], [Nb(CO)3(PMe3)4][Nb(CO)5(PMe3)], dagger [Nb(eta-C7H7)(CO)2(PMe3)], [Nb(eta-C6H5Me)2X] (X = Br, I, Me, Ph or CH2Ph), [{Nb(eta-C6H5Me)(mu-SR)2}2] (R = CH2Ph, Me or Bu) and [{Mo(eta-C6H5Me)(mu-SePh)2}2][PF6]2 have been prepared (dagger indicates the crystal structure has been determined). Evidence for the anions [Nb(eta-C6H5Me)(PMe3)3]- and [Nb(eta-C6H5Me)(tmps)]- is presented.
