  The role of lithium 1,3-bis(trimethylsilyl)-1-aza-allyls in phosphorus chemistry

  摘要：

  Treatment of the lithium 1-aza-allyl [Li{N(R)C(Bu-t)CHR}](2) 1, abbreviated as [<(Li(L)over bar>L')](2), with PCl3 gave in poor yields the trans-P,P'-dichlorodiazaphosphetidine C<(IPN(R')P(Cl)N)over bar>R' 3 (R=SiMe3, R'=C(Bu-t)=C(H)SiMe3). An improved route to 3 was based on [{Cu(mu-LL')}(2)] and PCl3; but the method of choice involved conversion of 1 into successively the imine RN=C(Bu-t)CHR2 4 (which upon heating gave the isomeric enamine 5) and Cl2PN=C(Bu-t)CHR2 6 and thermolysis of 6. The imine RN=C(Bu-t)CH(R)PPh2 7, obtained from [<(Li(L)over bar>L')](2) 1 and Ph2PCl, was isomerised into the Z-enamine R2NC(Bu-t)=C(H)PPh2 8, which upon irradiation gave a mixture of 8 and its E-isomer 9. Treatment of 7 with R '' PCl2 or PCl3 gave the cyclic phosphonium chlorides [Ph-2<(PP(R '')N(H)C(Bu-t)=C)over bar>H]Cl (10 R ''=Ph, or 11 R ''=Et) or [Ph-2<(PP(Cl)N(R)C(Bu-t)=C)over bar>H]Cl 12; 12 with AgOSO2CF3 or Na[BPh4] afforded [Ph-2<(PP(Cl)N(R)C((BU)-B-t)=C)over bar>H]A (13 A=CF3SO3, or 14 A=BPh4). The enamines RN=C(Bu-t)CH(X)R (15 X=Cl, or 16 X=I) were obtained from 1 and POCl3 or ICI respectively, and the enamine R2NC(Ph)=CR2 17 was obtained from the lithium 1-aza-allyl[Li(N(R)C(Ph)CR2)(THF)] and CF3SO3SiMe3. Compounds 3-17 were characterised by multinuclear NMR spectroscopy and (in most cases) MS; while single crystal X-ray diffraction data are provided for 3 and 10.
