  • of the anion but no real tendency can be extracted as a function of chain length. In all series the general order of stability order is SCN− ≈ Br− < BF4− ≈ PF6− < CF3SO3− < (CF3SO2)2N−. To avoid any phenomenon related to the sample preparation (purification, crystallisation, hydration) our reported

Graphical Abstract
  • of ionophore-based ISEs [54] and traditional Ag2S-based [58][59] ISE is largely eliminated in the present of ISEs (logK≤−1.4). It is reasoned that those ions with high hydration energies, such as Na+, K+, NH4+, Ca2+, Mg2+, Pb2+ and most of divalent transition metal ions, can not strongly interact

Although verification of this protocol was undertaken on a cycloheptanone derivative, substrate 39 failed to give the desired furan 42 (Scheme 6). Instead, hydration was observed as the major reaction pathway (i.e. 40) with furan 41 being

Graphical Abstract
  • -mediated hydrolysis led to formation of the N-benzoylaminosulfone 11, presumably by a sequence involving ring-opening by elimination, hydration of the electron-deficient alkenyl sulfone double bond and retro-aldol-like fragmentation. Reductive deprotection proved to be a more fruitful avenue of study
