Azasulfur(iv) derivatives of sulfite and sulfinate esters by formal S-S bond insertion of dichloramines.

Azasulfur(vi) compounds such as sulfoximines and sulfonimidamides are attractive due to the unique properties of the S[double bond, length as m-dash]N bond. While the synthesis of these carbon-attached sulfonimidoyl derivatives is well-established, the situation is different for their heteroatom-bound counterparts. In this work, we propose azasulfur(iv) esters as platform chemicals that can be derivatized to obtain all types of S[double bond, length as m-dash]N functional groups, among these are the poorly accessible, all-heteroatom imidosulfate esters.

Oxygen Surface Exchange and Tracer Diffusion in Differently Oriented Thin Films of Gd-Doped CeO.

The exchange of O between gaseous molecular oxygen and thin-film samples of CeGdO with two different, nominal surface orientations [(111) and (110)] was studied. Oxygen isotope exchange experiments were conducted in the temperature range of 573 ≤ /K ≤ 673 at an oxygen activity of O = 0.2.
