摘要：

(Cyanomethylene)triphenylphosphorane (5) adds borane (from 2) with formation of phosphorane - borane 6, which cannot be rearranged. 6 reacts with butyllithium to afford a crystalline lithium compound 9, which contains four tetrahydrofuran molecules. The X-ray structure analysis of 9 is reported. 9 is acting as a reducing agent towards halogeno and carbonyl compounds.
