Spectroscopic Studies on Sulphur Compounds. VI. On Silyl Tautomerism in Bis-trimethylsilylated Sulphinic AmidesThe bis-trimethylsilylated sulphinic amides 1 and 2 (eq. 1) as well as the sulphenic amide 4 (eq. 2) have been prepared for the first time and their structures deduced from lH n.m.r., 29Si n.m.r., i.r., and mass spectra. The imidate structure B (scheme 1) has been assigned unequivocally to compounds 1 and 2. The same structure is suggested for the known compound 3 on the basis of its spectroscopic behaviour. 29Si n.m.r. spectra are recorded for several reference compounds.
Notes:
Die zweifach trimethylsilylsubstituierten Sulfinamide 1 und 2 (Gl. 1) sowie das Sulfenamid 4 (Gl. 2) wurden erstmalig dargestellt und über 1H-NMR-, 29Si-NMR-, IR-und Massenspektren charakterisiert. Demnach liegen die Verbindungen 1 und 2 eindeutig, die bereits bekannte Verbindung 3 mit hoher Wahrscheinlichkeit in der N,O-silylsubstituierten Imidform B (Schema 1) vor. Die 29Si-NMR-Spektren einer Reihe von Vergleichssubstanzen werden mitgeteilt.
