摘要：

Molecular aluminum hydride [(L) AlH2] (L = Me(3)TACD) reacted with 2 equiv. of BPh3 in THF or THP to give the cationic alkoxides [(L) Al(OR)][HBPh3] (R = nBu, nPent) by facile ring-opening of the cyclic ethers. The C-alpha-O bond cleavage which involves the isolable intermediate [(L) AlH][HBPh3] is a result of hydride transfer to C-alpha from [HBPh3](-).
