(NH<sub>4</sub>)<sub>2</sub>[Tc<sub>2</sub>O<sub>2</sub>(S<sub>2</sub>O<sub>7</sub>)<sub>4</sub>]: An Unexpected Technetium(V)-Sulfate From the Reaction of (NH<sub>4</sub>)(TcO<sub>4</sub>) With SO<sub>3</sub>. [PDF]

open access: yesChemistry
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

The Sulfonation of Acetone: Characterization of Acetonedisulfonic Acid and Its Salts. [PDF]

open access: yesChempluschem
Acetonedisulfonic acid and some of its salts were structurally elucidated. Depending on the counterion, either strong hydrogen bonding or different coordination behaviors are found, showing the potential tunability of functionalized (organo)sulfonates. We report the synthesis of acetonedisulfonic acid ([(HOSO2CH2)2CO], ADSA) by slow reaction of acetone
