and amido−dihydrogen−monohydride tautomers. The crystal structures of [(COD)Ir(1S,2S)-Ph2PCH(Ph)CH(Me)NHCH2Ph}]BF4·2THF, [(COD)Ir1R,2S-Ph2PCH(Ph)CH(Me)NHMe}]BF4·THF, and the orthometalated 18e IrI complex [(COD)Ir(1R,2S)-Ph2PCH(C6H4-o)CH(Me)NHCHMe2}], which resulted from treatment of [(COD)Ir(1R,2S)-Ph2PCH(Ph)CH(Me)NHCHMe2}]BF4 with excess KOH, have been determined by single crystal X-ray diffraction
一般类型 [(COD)Ir(P∩NR1R2)]BF4 的手性和非手性 P,N 螯合 IrI 配合物,其中 COD = η4-1,5-C8H12 和 P∩NR1R2 = (1R,2R)-, ( 1S,2S)-, 或 (1R,2S)-Ph2PC1H(Ph)C2H(Me)NR1R2 (NR1R2 = NH2, NHMe, NHCH2Ph, NHCHMe2, NMe2), Ph2PCH2CR2NH2 (R = H, Me), 或 2-Ph2PC6H4NHMe,已经通过在 THF 中用所需的 β-氨基膦处理 [Ir(COD)2]BF4 来制备。单锂化配体 Ph2PCH2CMe2N(Li)H 和 2-Ph2PC6H4N(Li)Me 与 [(COD)Ir(μ-Cl)}2] 相互作用,得到中性烷基和芳基酰胺化合物 [(COD)Ir(Ph2PCH2CMe2NH)]和 [(COD)Ir(2-Ph2PC6H4NMe)]。所有
