WebApr 22, 2008 · Chiral enantiopure 1-alkyl-2,5-diphenylphospholanium salts were obtained in one step through alkylation of phospholane with alkyl triflates. The resulting air-stable phosphonium salts are electron-rich trialkylphosphane precursor ligands for transition metals, and they offer a convenient route toward chiral quaternary phosphonium salts as … Webphospholane concentrations are not necessarily ideal mixtures and thus may form azeotropes. The flammability of the considered electrolytes was deter-mined by the self-extinguishing method (SET), in this case, mainly susceptible to phosphorus and fluorine atom(s) in the phospholane structure (Figure 1b)).[13] Both atoms are able to
