Abstract: High Resolution Image Download MS PowerPoint Slide 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 K 3 As 7 with benzyl azide (BnN 3 ) leads to fragmentation of the [As 7 ] 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.
