我们曾研究了硼氢化钾与四乙基氯化铵在一定量水存在下的热解反应,制得了B_(10)H_(10)~(2-)、B_(12)H_(12)~(2-)等多面体硼氢化合物,并提出了热解反应的历程。在少量水存在下,通过三烷基苄基氯化铵与硼氢化钾反应,合成了四氢硼酸三烷基苄基铵R_3(C_6H_5CH_2)NBH_4。但热解该类型四氢硼酸盐时,得不到B_(10)H_(10)~(2-)、B_(10)H_(12)~(2-)等多面体硼氢化合物,而是苄基与氮相连的C—N键断裂形成的R_3N·BH_3配合物和甲苯。本文研究C_5H_5FeC_5H_4CH_2NMe_2(R)Cl与KBH_4在水溶液中
We have studied the pyrolysis reaction of potassium borohydride with tetraethylammonium chloride in the presence of a certain amount of water to prepare B_ (10) H_ (10) ~ (2), B_ (12) H_ (2-) and other polyhedral borohydride compounds, and proposed the pyrolysis reaction process. Trialkylbenzylammonium tetrahydroborate R_3 (C_6H_5CH_2) NBH_4 was synthesized by the reaction of trialkylbenzylammonium chloride with potassium borohydride in the presence of a small amount of water. However, the pyrolytic polyhydrolybdates such as B_ (10) H_ (10) ~ (2 -), B_ (10) H_ (12) ~ The R_3N · BH_3 complex formed by the cleavage of the C-N bond between benzyl and nitrogen and toluene. In this paper, C_5H_5FeC_5H_4CH_2NMe_2 (R) Cl and KBH_4 in aqueous solution
