## Abstract

Easily accessible dichloroarsanes are suitable precursors for the synthesis of rarely explored triazaarsoles, the arsenic analogues of tetrazoles and triazaphospholes. Calculations on the DFT level gave insight into the electronic structure of such planar compounds, indicating a high degree of aromaticity. Our preliminary investigations pave the way for accessing and investigating a whole variety of new heterocycles that contain a low‐coordinated arsenic atom.

Easily accessible dichloroarsanes are suitable precursors for the synthesis of novel triazaarsoles, the arsenic analogues of tetrazoles and triazaphospholes. Our findings pave the way to access and fully investigate such aromatic arsenic heterocycles in detail.
