Preparations using acetic anhydride as solvent are reported for B2O(O2CMe)4, AlCl(O2CMe)4, [TiO(O2CMe)2]. Ti(O2CMe)4·2MeCO2H, and M(O2CMe)4(M = Zr, Si, Ge, Sn, or Pb). Conductimetric titrations against potassium or tetramethylammonium acetate indicate the formation of [B2O(O2CMe)5]–, [B2O(O2CMe)6]2–, [M2(02CMe)9]–, [M(O2Me)5]–, and [M(02CMe)6]2–(M = Si. Ge, Sn. and Pb); the salts Na[B2O(O2CMe)5], and
报道了使用乙酸酐作为溶剂的B 2 O(O 2 CMe)4,AlCl(O 2 CMe)4,[TiO(O 2 CMe)2 ]的制备。Ti(O 2 CMe)4 ·2MeCO 2 H和M(O 2 CMe)4(M = Zr,Si,Ge,Sn或Pb)。对乙酸钾或乙酸四甲基铵的电导滴定表明[B 2 O(O 2 CMe)5 ] –,[B 2 O(O 2 CMe)6 ] 2–,[M 2(0 2 CMe)9 ] –,[M(O 2 Me)5 ] –和[M(0 2 CMe)6 ] 2 –(M =硅锗,锡和铅);盐Na [B 2 O(O 2 CMe)5 ]和K 2 [M(O 2 CMe)6 ](M = Si,Ge,Sn或Pb)。分离出了K 2 [Sn(O 2 CMe)]·(MeCO)2 O和[NMe 4 ] [Sn(O 2 CMe)5 ]。讨论了溶剂系统性质的证据。
