The Coordination Chemistry of Phospha- and Arsachalcoethynolates and the Quest to Generate Cyaphide and Cyarside

这个方案的目的是探索氰酸盐、PCE-和ASCE-(E=O，S，Se，可能是Te)的重同系物的配位化学。该项目将从优化和放大这些阴离子的合成开始，并将包括合成未知碲同系物的研究。对这类阴离子配位化学的研究将比较它们与氰酸盐和磷酰乙醇酯、PCO-的成键和桥联模式。后续的研究将集中在它们的配位、氧化、还原和光解上，以努力削弱和裂解碳-硫键。我们将通过形成这些不常见的阴离子的络合物和盐类来研究由此生成的Cp-和Cas-这两种不常见的蓝色素和氰苷配体。这项建议的最终范围是为磷酸盐和硫代乙炔酸盐的化学奠定基础，并可靠地产生氰化物和氰苷配体。

The goal of this proposal is to explore the coordination chemistry of the heavy homologues of cyanate, PCE– and AsCE– (E = O, S, Se, possibly Te). The project will commence with the optimisation and up-scaling of the synthesis of these anions and will include studies to synthesise the unknown tellurium homologue. Studies of the coordination chemistry of this family of anions will compare their bonding and bridging modes with cyanate and phosphaethynolate, PCO–. Subsequent research will focus on their coordination, oxidation, reduction and photolysis in an effort to weaken and cleave the carbon–chalcogen bond. The thereby generated cyaphide and cyaarside ligands, CP– and CAs–, respectively, will by studied through the formation of complexes and salts of these uncommon anions. The ultimate scope of this proposal is to lay the foundations in the chemistry of phospha- and arsachalcogenoethynolates and to reliably generate cyaphide and cyaarside ligands.
