Me3SiCH2As(SiMe3)2 (V). The monosilylated arsine was not isolated when 1 equiv. of Me3SiCl was allowed to react with combined II and n-BuLi (1 : 1 mole ratio); rather, a mixture of II and V resulted. Attempted preparations of (Me3SiCH2AsGaPh)n, are described. The ring compound, VI, was prepared by reaction of I with a mixture of Me3SiCl and Mg in THF. The molecular structure of this cycloarsane was determined by single-crystal

AsH2(II),并且II与Ph3Ga反应生成了[Me3SiCH2(H)AsGaPh2] 3(III),其特征在于进行了部分元素分析(C和H) ,1H NMR光谱和低温分子量测定。根据1 H NMR数据,通过II与Me3Ga的反应生成[Me3SiCH2(H)AsGaMe2] 3(IV)。但是,在允许H2,Me4Si,(Me3SiCH2As)5(VI)和未反应的(Me3SiCH2)3Ga与II反应后,只能鉴定出H2,Me4Si,(Me3SiCH2As)3(Ga)。2当量的反应 将Me 3 SiCl与II和n-BuLi的混合物(1∶2摩尔比)混合,得到Me 3 SiCH 2 As(SiMe 3)2(V)。当1当量时,未分离出单甲
