Organoarsenic chemistry was actively studied until the middle of 20th century. Although various properties of organoarsenic compounds have been computationally predicted, for example, frontier orbital levels, aromaticity, and inversion energies, serious concern to the danger of their synthetic processes has restricted experimental studies. Conventional synthetic routes require volatile and toxic arsenic precursors. Recently, nonvolatile intermediate transformation (NIT) methods have been developed to safely access functional organoarsenic compounds. Important intermediates in the NIT methods are cyclooligoarsines, which are prepared from nonvolatile inorganic precursors. In particular, the new approach has realized experimental studies on conjugated arsenic compounds: arsole derivatives. The elucidation of their intrinsic properties has triggered studies on functional organoarsenic chemistry. As a result, various kinds of arsenic‐containing π‐conjugated molecules and polymers have been reported for the last few years. In this minireview, progress of this recently invigorated field is overviewed.
Safety first! The development of practical synthetic tools successfully avoid conventional, dangerous routes to access various organoarsenic materials. Accordingly, functional organoarsenic chemistry is an emerging field (see figure). Recent advances in arsenic‐containing conjugated molecules, complexes, and polymers are discussed.
