which establishes between, on the one hand, one of the former species and, on the other hand, 1,2(7,12)-(Me(2)S)(2)B(12)H(10) (2-4) and [1,2(7,12)-(MeS)(2)B(12)H(10)](2-) (9-11). A boronated phosphonate 1-(MeS(CH(2))(4)P(O)(OEt)(2))-7-(Me(2)S)B(12)H(10) (14g) and a gem-bisphosphonate 1-(MeS(CH(2))(3)CH[P(O)(OEt)(2)](2))-7-(Me(2)S)B(12)H(10) (14h) were prepared from thioether 7 and the corresponding
通过甲基硫醚 [MeSB(12)H(11)](2-) (5)、[1-(MeS)-2(7,12)-(Me(2) )S)B(12)H(10)](-) (6-8) 和 [1,2(7,12)-(MeS)(2)B(12)H(10)](2- ) (9-11) 在乙腈中使用烷基卤化物和甲苯磺酸盐。由于这些甲基硫醚可以很容易地以富含 B-10 的形式大规模制备,并且由于它们的化学多功能性,它们是潜在非常有吸引力的硼实体,用于设计和合成用于癌症硼中子捕获疗法的疗法。发现 6-8 的烷基化可能因平衡而变得复杂,该平衡一方面是前一种物质,另一方面是 1,2(7,12)-(Me(2) S)(2)B(12)H(10) (2-4) 和 [1,2(7,12)-(MeS)(2)B(12)H(10)](2-) (9 -11)。硼化膦酸酯 1-(MeS(CH(2))(4)P(O)(OEt)(2))-7-(Me(2)S)B(12)H(10)
