The fungicidal bioactivity of a number of (E)-4-hydroxy-3'- and/or 4'-substituted stilbenes and related analogues was measured against the white-rot fungus Coriolus versicolor and the brown-rot fungi Gloephyllum trabeum and Ploria placenta using the agar

An efficient and simple one-pot procedure for selective etherification of 2-aryl-ethylalcohols has been achieved through Amberlyst 15-catalyzed reaction in dimethyl carbonate (DMC). Moreover, the polymer catalyst could be recovered and reused with no effect on its activity. The reaction mechanism involves the formation of phenonium ion which has been demonstrated by a C-C bond forming reaction. Theoretical studies are in agreement with and thus explain experimental results.

A method for selective dehydrogenation of a compound, comprising contacting a compound of the formula STR1 wherein each R1, R2, R3 and R4 is independently selected from the group consisting of H, (C1 -C20) alkyl, (C3 -C20) cycloalkyl, (C6 -C20) aryl, (C7 -C20) alkylaryl, (C7 -C20) aralkyl groups, as well as substituted (C1 -C20) alkyl, (C3 -C20) cycloalkyl, (C6 -C20) aryl, (C7 -C20) aralkyl and (C7 -C20) arylalkyl moieties, optionally further substituted with --OR, wherein R is R1, R2, R3 or R4 ; and wherein R1 and R2 or R3 and R4 may be joined as part of a ring structure, at a dehydrogenation temperature in the presence of a catalyst comprising about 0.01 wt %-19.9 wt % Pd and about 0.01 wt %-19.9 wt % Cu on a carbon support, wherein the total amount of (Pd+Cu) on the support is about 0.02 wt % to 20 wt %, the weight ratio of Pd:Cu is about 1:1 to 10:1, and the carbon support has a surface area of at least about 100 m2 /g and is essentially free of reactive sulfur. A selective dehydrogenation catalyst having the composition described supra is disclosed as is a method of preparing the same. This catalyst is highly selective for dehydrogenating a variety of substrates while minimizing the formation of unwanted hydrogenolysis by-products.
