Benzyl alcohol
Recent Literature
A transition-metal- and catalyst-free hydrogenation of a wide range of aryl
halides is promoted by bases using either aldehydes or alcohols as hydrogen
source. One equivalent of benzaldehyde affords an equal yield as that of 0.5
equiv of benzyl alcohol. The kinetic study reveals that the initial rate of
PhCHO is nearly 4 times faster than that of BnOH. Radical trapping experiments
indicate the radical nature of this reaction.

A simple ruthenium catalyst achives a semihydrogenation of diaryl alkynes to
the corresponding E-alkenes in very good yields using alcohols as the hydrogen
source. Best results were obtained using benzyl
alcohol as the hydrogen donor, although biorenewable alcohols such as furfuryl
alcohol could also be applied.
