The preparation of the crystalline diphenylketiminoboron dihalides (Ph2C:NBX2)n(X = Cl, Br, or I) from ethereal Ph2C:NLi and BX3 is described. The difluoride (Ph2C:NBF2)n, difficult to separate from LiF when similarly prepared, is better obtained from (n/3)(Ph2C:N)3B +(2n/3)BF3,OEt2. Cryoscopic, i.r., and mass spectroscopic evidence is presented indicating dimeric structures (n= 2) for X = I, Br, and
描述了由醚Ph 2 C:NLi和BX 3制备结晶二苯基酮亚氨基硼酸二卤化物(Ph 2 C:NBX 2)n(X = Cl,Br或I)。由(n / 3)(Ph 2 C:N)3 B +(2 n / 3)BF 3,OEt可以更好地获得类似地制备时难以与LiF分离的二氟化物(Ph 2 C:NBF 2)n。2。给出了低温,红外和质谱证据,表明二聚体结构(n= 2),对于X = I,Br,也可能是Cl。二氟化物的缔合程度不确定。
