unsymmetrical telluroether ligands, N,N-dimethyl-2-(phenyltellanyl)aniline (12), N,N-dimethyl-2-(o-tolyltellanyl)aniline (13), 2-((2,6-dimethylphenyl)tellanyl)-N,N-dimethylaniline (14) and 2-((2,6-diisopropylphenyl)tellanyl)-N,N-dimethylaniline (15), which contain one coordinating group with an sp3 N-donor atom, were treated with Pd(COD)Cl2, the palladium telluroether complexes of the form Pd(2-NMe2CH2C6H4)(R)TeCl2
摘要合成了两个新的不对称硒醚配体,即N,N-二甲基-2-(邻甲苯基硒基戊基)苯胺(10)和2-((2,6-二甲基苯基)硒基)-N,N-二甲基苯胺(11)。 N,N-二甲基苄胺通过邻位锂化途径。当用Pd(COD)Cl2(COD = 1,5-环辛二烯)处理配体10和11时,反应生成Pd(2-NMe2CH2C6H4)(R)SeCl2形式的新型Pd(II)配合物,其中R = 2 -MeC6H4(16)和2,6-MeC6H3(17)。类似地,当非对称的碲醚醚配体时,N,N-二甲基-2-(苯基碲烷基)苯胺(12),N,N-二甲基-2-(邻甲苯基甲苯基)苯胺(13),2-(((2,6-二甲基苯基)处理了含有一个带有一个sp3 N-给体原子的配位基团的)tellanyl)-N,N-二甲基苯胺(14)和2-((2,6-二异丙基苯基)tellanyl)-N,N-二甲基苯胺(15)与Pd(COD)Cl2 Pd(
