The approach of using RE-TMS reagents is readily adaptable to introduce specific chemical functionality in R, and has thus been extended to the synthesis of ternary CuHg E nanoclusters via the use of silylated copperchalcogenolate complexes, [(L)3Cu(E-TMS)] (E = S, Se, Te L = PPr", PEts) (Figure 3) as soluble delivery agents of CuE (Equation (IQ). Silylated ferro-cenyl-selenolate reagents have also been used to introduce redox-active ferrocene units onto copper selenium cluster cores (Equation (17)) ...
