Abstract
Cyclopentadienyl anions ([Cp]-) are pervasive ligands in coordination chemistry. In contrast, heavy-element derivatives of these ligands, particularly those that feature arsenic, are not as well developed. In this work, a new arsenic-based heterocycle with a structure analogous to [Cp]- is presented. Reaction of K3As7 with benzyl azide (BnN3) leads to fragmentation of the [As7]3- core and C-H activation of two [BnN] units to give the five-membered arsenic heterocycle [As(NC(Ph))2]-. This arsenic heterocycle was studied by nuclear magnetic resonance and UV-vis spectroscopy, X-ray diffraction, and its electronic structure was investigated computationally.
期刊介绍:
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
