H2-Free Re-Based Catalytic Dehydroxylation of Aldaric Acid to Muconic and Adipic Acid Esters

As one of the most demanded dicarboxylic acids, adipic acid can be directly produced from renewable sources. Hexoses from (hemi)cellulose are oxidized to aldaric acids and subsequently catalytically dehydroxylated. Hitherto performed homogeneously, we present the first heterogeneous catalytic process for converting an aldaric acid into muconic and adipic acid. The contribution of leached Re from the solid pre-reduced catalyst was also investigated with hot-filtration test and found to be inactive for dehydroxylation. Corrosive or hazardous (HBr/H2) reagents are avoided and simple alcohols and solid Re/C catalysts in an inert atmosphere are used. At 120 °C, the carboxylic groups are protected by esterification, which prevents lactonization in the absence of water or acidic sites. Dehydroxylation and partial hydrogenation yield monohexenoates (93 %). For complete hydrogenation to adipate, a 16 % higher activation barrier necessitates higher temperatures.

Oxidative addition of benzyliminium tetraphenylborate to Pd(dba)(dppe): Synthesis and catalytic activity of [(dppe)Pd(dba)-{η1(N)-PhCH2N=CMe2}] (BPh4)2

The synthesis and catalytic activity of the new dicationic Pd11 complex [(dppe)Pd(dba){η1(N)-PhCH2N=CMe2}] (BPh4)2 from the Pd0 complex Pd(dba)(dppe) and [(PhCH2)HN= CMe2]BPh4 are described. [(PhCH2)HN=CMe2]BPh4 adds to Pd(dba)(dppe) under mild conditions through a selective N-H activation. The resulting species further reacts with [(PhCH2)HN=CMe2]BPh4 and generates N-benzyl-N-isopropylamine and [(dppe)Pd(dba){η1(N)-PhCH2N= CMe2}](BPh4)2. The latter catalyzes the dimerization of methyl acrylate (MA) and the co-oligomerization of MA with styrene. Significant changes of the selectivity in the dimerization of MA have been found, e.g. changing the solvent from methyl acrylate (mostly tail-to-tail, T-T, coupling) to the ionic liquid [bmim]BF4 (T-T and head-to-tail, H-T, coupling).
