“…Although the details of this transformation remained unclear, we hypothesize that 21 partially degraded to give a nucleophilic species corresponding to X 2 N–CN (with unknown X), which then added to the carbon the N –CN unit of remaining 21 to give 22 . In general, reactions of N -cyano groups of sulfoximines are well established bringing the aforementioned proposal in line with previous work. − …”

New sulfur-containing inorganic−organic hybrid polymers featuring B�N and B−O linkages are described. Sulfones, sulfoximines, and sulfoxides have been used as sulfur core units. An analogous sulfilimine proved unsuitable leading to an unprecedented side product. Aryl bromoboranes served as starting materials for the B�N and B−O linkages. For each polymer, the respective lowmolecular-weight analogues were studied. Finally, degradation studies showed that the sulfur units can be regenerated by pH changes suggesting the new materials to be applicable in drug release programs.
