WebJan 15, 2024 · Only a handful of remarkable iron catalysts, namely, an iron-salen complex reported by Katsuki and co-workers [46,47], a chiral diphosphine oxide–iron(II) complex developed by the Ishihara group , and an iron-chiral phosphoric acid (CPA) catalyst introduced by the Pappo group [49,50], have been disclosed to date (Figure 2a). WebThis reaction is reminiscent of the Swern oxidation . The desiccating power of P 4 O 10 is strong enough to convert many mineral acids to their anhydrides. Examples: HNO 3 is converted to N 2 O 5 ; H 2 SO 4 is converted to SO 3 ; HClO 4 is converted to Cl 2 O 7 ; CF 3 SO 3 H is converted to (CF 3) 2 S 2 O 5 . As a proxy measurement [ edit]
