Abstract

8-Tetrahydrofuronium and 8-tetrahydropyronium derivatives of iron bis(dicarbollide)(-I) were synthesized. Their reactions of ring cleavage by MeOH, N3(-), amines and 1,2-bis(diphenylphosphino)ethane were investigated. 8-Tetrahydrofuronium iron bis(dicarbollide)(-I) was found to be more active in these reactions in comparison with 8-tetrahydropyronium and 8-dioxonium species, respectively. The first conjugates of iron bis(1,2-dicarbollide)(-I) with 2'-deoxyadenosine modified via the C-8 position of the purine base were synthesized. Reactions of these oxonium compounds with 1,2-bis(diphenylphosphino)ethane (dppe) led to zwitter-ionic monophosphonium salts. One of these compounds has given rise to a novel ferracarborane/cobaltacarborane hybrid complex.

摘要

合成了双（二碳硼烷）铁（-I）的8-四氢呋喃鎓和8-四氢吡喃鎓衍生物。研究了它们与甲醇、N3（-）、胺和1,2-双（二苯基膦基）乙烷的开环反应。发现8-四氢呋喃鎓双（二碳硼烷）铁（-I）在这些反应中分别比8-四氢吡喃鎓和8-二氧鎓物种更具活性。合成了双（1,2-二碳硼烷）铁（-I）与通过嘌呤碱基的C-8位修饰的2'-脱氧腺苷的首批缀合物。这些氧鎓化合物与1,2-双（二苯基膦基）乙烷（dppe）的反应生成两性离子单鏻盐。其中一种化合物产生了一种新型的铁碳硼烷/钴碳硼烷杂化配合物。
