2- benzyl alcohol buffer solution

TABLE 9. Oxidation of X-substituted benzyl alcohols with Trametes villosa laccase and R2NO—H mediators in buffered (pH = 4.5) water solution at 25 °C. Comparison of p (vs. independently generated in MeCN solution at 25 °C 

Later in the same year, Uozumi, Yamada, and co-workers also reported an inwater dehydrative A(-alkylation reaction under air using a heterogeneous boron-iridium heterobimetallic Polymeric Catalyst 34 (Scheme 35) [184]. This method is suitable for the reactions of benzylic and aliphatic alcohols with ammonia, and primary, secondary, and cyclic amines. Different to usual hydrogen autotransfer reactions, which require basic conditions, the reactions of benzylic, aliphatic, and secondary amines and ammonia require a pH 4 aqueous buffer solution under microwave conditions. The catalyst can be recovered and reused at least twice without loss of activity.
