trans-dioxo-complexes [OsO2(O2R)(NC7H13)L]. The adduct OsO4·NC7H13 reacts with dienes R (R = cyclohexa-1,3-diene, cyclo-octa-1,5-diene, or 2,5-dimethylhexa-2,4-diene) to give products [Os2O4(O4R)(NC7H13)2}n] or [OsO2(O2R)(NC7H13)}2]. With alkynes R they give [Os2O4(O4R)(NC7H13)2}n]·nS (R = C2H2, S = benzene, toluene, or carbon tetrachloride) and [Os2O4(O4R)(NC7H13)2}n](R = PhC2H); these products
of(VI)酯络合物[OsO 2(O 2 R)(NC 7 H 13)} 2 ]是通过单烯烃R(R =环己烯,乙烯或二苯乙烯)与加合物OsO 4 ·NC 7 H反应形成的13(NC 7 H 13 =喹核苷)含有不对称的Os 2 O 2桥;在溶液中,它们具有五坐标单体结构。与叔胺L(L =吡啶,甲基咪唑,5,6-二甲基苯并咪唑或奎尼啶)一起,它们会给出相应的反式-二氧杂合物[OsO 2(O 2R)(NC 7 H 13)L]。加合物OsO 4 ·NC 7 H 13与二烯R(R =环己-1,3-二烯,环八-1,5-二烯或2,5-二甲基六-2,4-二烯)反应生成产物[Os 2 O 4(O 4 R)(NC 7 H 13)2 } n ]或[OsO 2(O 2 R)(NC 7 H 13)} 2 ]。使用炔烃R可以得到[Os 2 O 4(O 4 R)(NC 7 H 13)2} n ]· n S(R =
