Elementorganic Amine/Imine Compounds. XX. N,N′-Dimethyl-P,P-dialkyl-N-dimethylphosphinylaminoiminophosphoranes The reaction between H3C(R)P(NCH3)NCH3Li and dimethylchlorophosphine gives the N,N′-dimethyl-P,P-diakyl-N-dimethylphosphinylaminoiminophosphoranes 2 (R = CH3, C(CH3)3). 2 can be oxidized by elemental sulfur and selenium with formation of the double ylides H3C(R)P(NCH3)NCH3P(X)(CH3)2 (3) (R = CH3, C(CH3)3; X = S, Se). The NMR spectra of 2 and 3 are discussed.
Notes:
H3C(R)P(NCH3)NCH3Li bildet mit Dimethylchlorphosphin die N,N′-Dimethyl-P,P-dialkyl-N-dimethylphosphinyl-aminoiminophosphorane 2 (R = CH3, C(CH3)3). Ihre Oxydation mit elementarem Schwefel und Selen ergibt die Doppelylide H3C(R)P(NCH3)NCH3P(X)-(CH3)2 (3) (R = CH3, C(CH3)3; X = S, Se). Die NMR-Spektren von 2 und 3 werden diskutiert.
