LAH, Lithium aluminum hydride, Lithium tetrahydridoaluminate

LiAlH4 is a very common, strong reducing agent, which reduces a vast number of different functional groups.


Recent Literature


The preparation of alkenyl halides of any length from inexpensive starting reagents is reported. Standard organic transformations were used to prepare straight-chain α-olefin halides in excellent overall yields with no detectable olefin isomerization and full recovery of any unreacted starting material.

Trifluoromethyl arenes were reduced with lithium aluminum hydride to give toluene derivatives in good yields in the presence of 5 mol % of niobium(V) chloride. Stepwise, partial reduction of a bis(trifluoromethyl) arene  was also demonstrated.
