Catenated and spirocyclic polychalcogenides from potassium carbonate and elemental chalcogens
The reaction of potassium carbonate with elemental sulfur or selenium in acetone in the presence of [PPN]Cl (PPN = (Ph 3 P) 2 N) produces catena -[S 12 ] 2− , the longest structurally characterised polysulfide dianion, or spiro -[Se 11 ] 2− as ion-separated [PPN] + salts. Reaction of potassium carbo...
