四氢［^（10）B］硼酸四乙铵的合成

SYNTHESIS OF TETRAETHYL AMMONIUM[￣(10) B] BOROHYDRIDE

以［^（１０）Ｂ］硼酸为原料合成乙二醇甲醚［^（１０）Ｂ］硼酸酯，再与氢化铝锂和氯化四乙基铵反应合成四氢［^（１０）Ｂ］硼酸四乙铵，收率可达８０％以上。

A new preparative method of tetraethyl ammonium[￣(10)B] borhydride(1) from[(10)￣B] boric acid(2) was worked out 2,reacted with ethylene glycol mono methyl ether to form tri(ethylene glycol monomethyl ether)[￣(10)B] borate(3),then reacting with LiAIH4 and Et4 NCl,the title compound was afforded with a yield more then 80%.
