- W2023669096 abstract "Derivate NH-funktioneller Sulfinimidamide wurden durch Substitutions-, Additions-und Eliminierungsreaktionen synthetisiert. Substitutionsreaktionen primärer Sulfinimidamide RS(NH)NH2 (1), (R = t-Bu oder Ph) mit Aminostannan Me3SnNHt-Bu ergeben N,N,N′-tristannyl-substituierte Sulfinimidamide RS(NSnMe3)N(SnMe3)2 (2). Mit 1 und Säurechloriden entstehen lediglich Monosubstitutionsprodukte PhS(NR3)NH2 (3) (R3 = MeCO) und (4) (R3 = MeSO2). — Die Addition von Heterokumulenen PhNCZ and 1 führt zu 1:1-Addukten PhS(NC(Z)NHPh)NH2 (6) (Z = O) und (7) (Z = S). — Eliminierung von Isobuten aus S-t-Butyl-sulfinimidamiden t-BuS(NR1)NHR2 (8) (R1, R2 = t-Bu oder SiMe3) liefert primäre Diaminosulfane R1HNSNHR2 (9). Metallierung von 9 a (a: R1, R2 = t-Bu) mit MeLi und nachfolgende Metathese mit Me3SnCl führt zum N,N′-distannylierten Diaminosulfan (Me3Sn)t-BuNSNt-Bu(SnMe3) (10). Reactions with NH-functional Sulfur Nitrogen Compounds Derivatives of NH-functional sulfinimide amides were synthesized by substitution, addition, and elimination reactions. Substitution reactions of primary sulfinimide amides RS(NH)NH2 (1) (R = t-Bu or Ph) with aminostannane Me3SnNHt-Bu give N,N,N′-tristannyl-substituted sulfinimide amides RS(NSnMe3)N(SnMe3)2 (2). With 1 and acid chlorides only monosubstituted products PhS(NR3)NH2 (3) (R3 = MeCO) and (4) (R3 = MeSO2) are formed. — Addition of hetero cumulenes PhNCZ on 1 gives 1:1-adducts PhS(NC(Z)NHPh)NH2 (6) (Z = O) and (7) (Z = S). — Eliminating of isobutene from S-t-butyl-sulfinimide amides t-Bu-S(NR1)NHR2 (8) (R1, R2 = t-Bu or SiMe3) yields primary diaminosulfanes R1HNSNHR2 (9). Metallating of 9 a (a: R1, R2 = t-Bu) with MeLi followed by metathesis with Me3SnCl gives the N,N′-distannylated diaminosulfane (Me3Sn)t-BuNSNt-Bu(SnMe3) (10)." @default.
