germanes Ph3Ge[NHC(CH3)CHCN] and 2,6-dimethyl-4-(triphenylgermylamino)pyrimidine have been prepared and structurally characterized, and the conversion of Ph3GeCH2CN to Ph3Ge[NHC(CH3)CHCN] and 2,6-dimethylamino-4-(triphenylgermylamino)pyrimidine as well as the conversion of Ph3Ge[NHC(CH3)CHCN] to 2,6-dimethyl-4-(triphenylgermylamino)pyrimidine in acetonitrile solvent has been observed using 1H NMR spectroscopy
在锗酰胺和氢化锗之间的水蒸气热解反应过程中,观察到了3-氨基巴豆腈和4-氨基-2,6-二甲基氨基嘧啶的形成,或者以游离胺的形式或者以结合锗的配体的形式结合到锗上基地。这些物质是由乙腈的二聚或三聚产生的,并且仅在反应中使用在锗中心具有大的空间体积的锗酰胺时才被检测到。锗结合的3-氨基巴豆腈化合物的分离表明,由锗酰胺R 3 GeNMe 2与CH 3反应生成的α-锗烷基腈物种R 3 GeCH 2 CNCN溶剂也可以进一步与CH 3 CN反应,生成3-氨基巴豆腈和4-酰胺基2,6-二甲基氨基嘧啶类。制备了两种锗烷Ph 3 Ge [NHC(CH 3)CHCN]和2,6-二甲基-4-(三苯基锗基氨基)嘧啶,并进行了结构表征,并将Ph 3 GeCH 2 CN转化为Ph 3 Ge [NHC( CH 3)CHCN]和2,6-二甲基氨基-4-(三苯基锗氨基)嘧啶,以及在乙腈中将Ph 3 Ge [NHC(CH 3)CHCN]转化为2
