trans to methyl in a chelate ring may be displaced by glycinate N. 3. groups coordinated cis to methyl are not displaced at room temperature. When X = OH, ring closure to an isomer of PtMe2(gly)2 possible isomers of PtMe2(gly)2 with methyl groups cis (viz., the isomer with both N-atoms trans to methyl, and the isomer with one N-atom trans to methyl) may be obtained by reaction of the appropriate isomer
摘要研究了甘氨酸钠与PtMe2X(gly)(H2O)具有两个甲基和X互为顺式的三个异构体的反应(X = Br,OH; glyH =甘氨酸)。Bis-(甘氨酸盐)复合物PtMe2X(OH)(gly)2-2(两个不相同的N键合甘氨酸盐)或PtMe2X(gly)-2(一种螯合和一个不相同的甘氨酸盐)和tris-(甘氨酸盐)复合物PtMe2X(gly)根据规则形成2-3(三个不明的甘氨酸盐):1.甘氨酸盐N容易取代水配位为甲基的反式。2.如果使用过量的甘氨酸盐,则螯合物环中配位为甲基的甘氨酸O可以被置换的通过甘氨酸N。3.在室温下不取代与甲基配位的基团。当X = OH时,PtMe2(gly)2异构体的闭环可能是带有甲基顺式的PtMe2(gly)2异构体(即,通过使适当的PtMe2(gly)(H2O)+2异构体与甘氨酸在酸性溶液中反应,可制得具有两个N原子均转化为甲基的异构体和具有一个N原子均转化为
