摘要：

Alkylation of tantalum(III) arene complexes affords stable dialkyl and monoalkyl halide species (eta-6-C6Me6)Ta(DIPP)R2 (DIPP = 2,6-diisopropylphenoxide) and (eta-6-C6Me6)Ta(DIPP)RX. The alkyl hydride complexes (eta-6-C6Me6)Ta(DIPP)R(H) are also prepared from (eta-6-C6Me6)Ta(DIPP)RX and LiBEt3H. The arene ring in (eta-6-C6Me6)Ta(DIPP)Et2 exhibits a structure consistent with a diene-diyl distortion. The first evidence for the formation of a d1 arene species is presented in cyclic voltammetry experiments on these compounds.
