selenium resulted in the formation of novel dimeric compounds with the general formula [R2M(μ-SeR)]2 (M = In, R = Np (1); M = Ga, R = CH2SiMe3 (2)) in a nearly quantitative yield. Reaction of GaMes3 (Mes = 2,4,6-Me3C6H2) with 2 mol of elemental Se, and subsequent addition of 4-picoline (C6H7N), resulted in the isolation of three compounds, [(Mes)C6H7N·Ga-μ-Se]2 (3), (Mes)2C6H7N·GaSeMes (4), and Se2Mes2
InNp 3(Np = CH 2 CMe 3)和Ga(CH 2 SiMe 3)3与元素硒的独立1:1反应导致形成通式[R 2 M(μ-SeR)的新型二聚化合物] 2(M = In,R = Np(1); M = Ga,R = CH 2 SiMe 3(2))以接近定量的产率。GaMes 3(Mes = 2,4,6-Me 3 C 6 H 2)与2 mol元素硒的反应,然后添加4-picoline(C 6 H 7N),导致分离出[[Mes)C 6 H 7 N·Ga-μ-Se] 2(3),(Mes)2 C 6 H 7 N·GaSeMes(4)和Se 2这三种化合物混乱2。化合物3是硒桥联的二聚体,在二聚体单元中具有两个二配位的Se原子和两个4-甲基吡啶(C 6 H 7 N)分子。在相关工作中,InNp 3与S 2 Ph 2反应得到二聚体化合物[Np 2 In(μ-SPh)] 2(5),消除了NpSPh。的合成和表征1
