Protonated molecule
WebbProtonation of the HRu3(CO)11 anion at-60°C gives HRu3(COH)(CO)10 as the initial product, but at higher temperatures rearrangement to H2Ru3(CO)11 is observed The latter product is proposed to contain one bridging and one terminal hydridge ligand At 25°C H2Ru3(CO)11 decomposes rapidly to Ru3(Co)12 Webb24 feb. 2014 · An ion formed by interaction of a molecule with a proton abstracted from an ion, as often occurs in chemical ionization according to the reaction: M+ XH + → MH + + …

WebbFinal answer. Transcribed image text: When an NMR spectrum is taken of the molecule below, there is the expected 5H in the aromatic region, triplet (3H) and quartet (2H) upfield of the aromatic region. After adding a drop of acidic D2O, the spectrum changes over a few minutes to one that just has 5H aromatic protons and an upfield 3H singlet. WebbLe Gac, S., Boitrel, B., Sollogoub, M., & Ménand, M.
