This article outlines the synthesis and reactions of six-membered arsenic heterocycles with heteroatoms published mostly in the period 2007–17. The chemistry of six-membered arsenic heterocycles with heteroatoms is restricted mainly to oxa-, thia-, aza-, phospha-, and diarsinines. During the last decade, six-membered arsenic heterocycles with boron, aluminium, gallium, indium, silicon, tin, lead, and selenium atoms have appeared in the literature. Accordingly, these heterocyclic ring systems have been included in this article. © 2022 Elsevier Ltd. All rights reserved.
