Abstract

The mixed-ring beryllocene Be(C₅Me₅)(C₅Me₄H), that contains η⁵-C₅Me₅ and η¹-C₅Me₄H rings, the latter bonded to the metal through the CH carbon atom (X-ray crystal structure) reacts at room temperature with CNXyl (Xyl = C₆H₃-2,6-Me₂) to give an iminoacyl product, Be(η⁵-C₅Me₄H)[C(NXyl)C₅Me₅] derived from the inverted beryllocene structure Be(η⁵-C₅Me₄H)(η¹-C₅Me₅).
