Synthesis of a metal–organic framework (MOF)-supported olefin metathesis catalyst has been accomplished for the first time following a new, convergent approach where an aldehyde-functionalized derivative of Hoveyda’s recently reported ruthenium c

Superacids, defined as acids with a Hammett acidity function H0 ≤ -12, are useful materials, but a need exists for new, designable solid state systems. Here, we report superacidity in a sulfated metal-organic framework (MOF) obtained by treating th

Time-dependent 17O NMR spectra of basified decaniobate (Nb10O286–) solutions displayed intense resonances assigned to the well-known protonated hexaniobate anion (Nb6O198–) and two other species identified as heptaniobate (Nb7O229–) and protona
