Modular Approach to Heterogenous Catalysis. Manipulation of Cross-Coupling Catalyst Activity
摘要:
A new type of robust, heterogeneous, modular Pd catalyst with metal embedded in the gel matrix is presented. The regulatory element of its catalytic activity has been introduced via chemical changes in the gel. The concept is illustrated in a series of Suzuki-Miyaura cross-coupling reactions. The demonstrated catalyst activity variations depend on the structure of the gel.

A mild reduction of ortho-fluoro benzamides was discovered using LAH. The reaction proceeds cleanly and in moderate yields. The scope of the reaction is explored and a mechanism is proposed. A two carbon spacer between the amide and a 3° amine is optimal for this chelation controlled reaction.
