Arylsulfurdiimides: a new class of sulfur–nitrogen anion
Abstract
N-Aryl-N′-trimethylsulfurdiimides (aryl = 2,6-F2C6H3, 2-FC6H4) react with TASF to give quantitatively the corresponding TAS salts with the ArNSN– anions (2a, 2b), isoelectronic with arylthionylimides 3; because of the short terminal SN bond the anions should be regarded as thiazylamide rather than sulfurdiimide anions.
