of the proligand tris(2-pyridylthio)methane (HTptm) with various Alkaline Earth (AE) reagents: (1) dialkylmagnesium reagents and (2) AE bis-amides (AE = Mg–Ba). Heteroleptic complexes of general formulae [Mg(Tptm)(R)] (R = Me, nBu; Tptm = C(S–C5H4N)3}−) and [AE(Tptm)(N′′)] (AE = Mg–Ba; N′′ = N(SiMe3)2}−) were targeted from the reaction of HTptm with R2Mg or [AE(N′′)2]2. Reaction of the proligand
在这里,我们报告了前配体三(2-吡啶硫基)甲烷(HTptm)与各种碱土(AE)试剂的反应性:(1)二烷基镁试剂和(2)AE双酰胺(AE = Mg-Ba)。通式 [Mg(Tptm)(R)] (R = Me, n Bu; Tptm = C(S–C 5 H 4 N) 3 } - ) 和 [AE(Tptm)(N′′) 的杂配配合物] (AE = Mg–Ba; N′′ = N(SiMe 3 ) 2 } - ) 是 HTptm 与 R 2 Mg 或 [AE(N′′) 2 ] 2反应的目标。前配体与二烷基镁试剂的反应导致形成 [Mg(κ 3 C , N ,N –CBu}S–C 5 H 4 N} 2 )(μ-S–C 5 H 4 N)} 2 ] ( 1 ) 和 [Mg(κ 3 C , N , N –CMe }S-C 5 H 4 N} 2 )(μ-OSiMe 3 )} 2 ] ( 2 ) 分别是烷基转移到甲烷化物碳上并伴随
