  Improved processes for liberating boronic, RB(OR').sub.2, and borinic, RR'BOR', esters from their "ate" complexes, free of alcohol are provided. Pyrolysis of lithium organylborates LiRB(OR').sub.3 and LiRR'BOR', wherein R is an organyl group and R' is straight or branched-chain lower alkyl, directly yields the relatively volatile boronic and borinic esters in high purity, leaving behind a residue of lithium alkoxide. Treatment of the lithium organylborates with an appropriate acid halide cleanly liberates either volatile or non-volatile boronic or borinic esters, readily separated from the lower alkyl ester produced as a by-product. The novel compound lithium dimethylborohydride is also provided.

  提供了从其“ate”络合物中解放出无醇的硼酸酯，RB（OR'）2和硼烷酯，RR'BOR'的改进过程。锂有机硼酸盐LiRB（OR'）3和LiRR'BOR'的热解，其中R是有机基团，R'是直链或支链低级烷基，直接产生相对挥发性的高纯度硼酸酯和硼烷酯，留下锂烷氧化物残留物。用适当的酸卤处理锂有机硼酸盐可以干净地释放出挥发性或非挥发性的硼酸酯或硼烷酯，并容易与产生的低级烷基酯副产物分离。还提供了新型化合物锂二甲基硼氢化物。
