Novel α,ω-bis(trialkylsilyl)-allyl and -1-azapentadienyl ligands; structures of [Li{η3-CH(CHSiMe2But)2}(tmen)], [Li{N(SiMe3)CBut(CH)3SiMe2But}(tmen)] and [K{η4-N(SiMe2But)CBut(CH)3SiMe2But}]∞
摘要:
The eta(3)-allyl-lithium or -potassium compounds [Li{eta(3)-CH(CHSiMe(2)Bu(t))(CHSiMe(2)R)}(tmen)] (R = Bu(t) 3a, Me 3b) and K{eta(3)-CH(CHSiMe(2)Bu(t))(2)} (obtained from Bu(t)Me(2)SiCH(2)CH=CHSiMe(2)R) with Bu(t)CN afford the 1-azapentadienyl-lithium or -potassium compounds [Li{eta(1)-N(SiMe(2)R)C(Bu(t))(CH)(3)SiMe(2)Bu(t)}L] (L = tmen, R = Bu(t) 6a, Me 6b; L absent, R = Bu(t) 8a, Me 8b) or [K{eta(4)-N(SiMe(2)Bu(t))C(Bu(t))(CH)(3)SiMe(2)Bu(t)}](infinity) 7.
