Synthesis and NMR Spectra of λ5-Diphosphets. Structure of 2,4-Diphenyl-1,1,3,3-tetrakis (diethylamino)-1λ5, 3λ5-diphosphetePreparation, properties, and n.m.r. spectra of C2H5PF2[N(C2H5)2]2, CH2=PF[N(C2H5)2]2, and the diphosphetes {RC=P[N(C2H5)2]2}2 (R) = H (5a), CH3 [(5b)] are described. The λ5-diphosphete {HC=P(NR2)2}2 (R = CH3) reacts with BF3 · O(C2H5)2 to give which is transformed into by n-C4H9Li. The crystal and molecular structure of 2,4-diphenyl-1,3,3-tetrakis(diethylamino)-1λ5,3λ5-diphosphete 2 are reported and discussed.
Notes:
Darstellung, Eigenschaften und NMR-Spektren von C2H5PF2[N(C2H5)2]2, CH2=PF[N(C2H5)2]2 und der Diphosphete {RC=P[N(C2H5)2]2}2 (R = H )(5a), CH3 [(5b)] werden beschrieben. Das λ5-Diphosphet {HC=P(NR2)2}2 (R = CH3) reagiert mit BF3 · O(C2H5)2 zu das mit n-C4H9Li in übergeht. Die Kristall- und Molekülstruktur von 2,4-Diphenyl-1,1,3,3-tetrakis(diethylamino)-1λ5,3λ5-diphosphet 2 werden mitgeteilt und diskutiert.
