Abstract
In this brief review, synthesis, structural and reactivity aspects of heavier organochalcogen (RS+n, RSe+n, RTe+n;n = 1–3) cations have been described. The orgaosulfenium ions (RS+) and related sulfur cations have been already reported in detail and, therefore, will not be discussed here. Structurally characterised organochalcogen cations of heavier chalcogens (Se, Te) will be the main focus of the review and only a few relevant examples, which are not structurally characterized, will be discussed for comparison purposes. The collection of chalcogen cations enlisted here shall benefit the readers who are interested in isolating and utilizing the organochalcogen cations for particular applications.
