Chemistry of Reactive Cations Derived from Sulfur Dioxide Analogues, IV1). - N-Methyl-N-sulfinylmethanaminium Salts - Reactions with Carbonyl and Thiocarbonyl CompoundsN-Methyl-N-sulfinylmethanaminium tetrafluoroborate (1) reacts with aromatic aldehydes by elemination of SO2 to form the imonium salts 3, with thiones, dithiocarboxylic, and trithiocarbonic acid derivatives by formal loss of S2O to give the imonium salts 5, 7, 10, and 12. The rotation barrier around the CN bond has been determined for 10 as 69.5 and for 12 as 77.8 kJ/mol.
Notes:
N-Methyl-N-sulfinylmethanaminium-tetrafluoroborat (1) reagiert mit aromatischen Aldehyden unter SO2-Abspaltung zu den Imoniumsalzen 3, mit Thionen, Dithiocarbonsäure- und Trithio-kohlensäurederivaten unter formaler Abspaltung von S2O zu den Imoniumsalzen 5, 7, 10 und 12. Die Rotationsbarriere um die CN-Bindung wird für 10 zu 69.5 und für 12 zu 77.8 kJ/mol bestimmt.
