The reduction of carboxylic acid esters to alcohols is commonly effected with a stoichiometric amount of a highly reactive metal-hydride reagent (e.g.LiAlH4).The amount of waste generated by this procedure would decrease strongly through the use of H2 as the reducing agent.The homogeneous ...
A novel and efficient procedure for the preparation of allylic alcohols from α,β-unsaturated carboxylic esters using LiAlH4/BnCl A new and efficient method for the reduction of α,β-unsaturated carboxylic esters to allylic alcohols utilizing LiAlH4/BnCl is described. Various α,β-u... X Wan...
methyl sulfide and LiAlH4 differ considerably in their reactivity toward other functional groups5, the borane methyl sulfide reagent constitutes a valuable alternative to LiAlH4 for chemically modifying nitroxide carboxylic acids which also bear other functional groups susceptible toward reduction by LiAlH4...

An interesting, recently reported complementary observation is that the superacid CF3SO3H (trifluoromethanesulfonic acid; triflic acid) is able to protonate cations such as 6.59 Dicationic species are thus produced, with ring-opening occurring at the distal cyclopropane CC bond, which...
