    • This proposal does not explain why water, one of the products of hydrogen peroxide disproportionation, would not inhibit formation of the Pd(II)-alkoxide intermediate.

    • MS3A are molecular sieves of the A-type zeolite with 3 Å pores arising from the partial substitution of potassium for sodium ions in the aluminosilicate lattice. For detailed descriptions of molecular sieves and other zeolites, see ref 18.

    • 3b the Chibenzaldehyde ratio was 1:1 in the absence of molecular sieves and 2:3 in the presence of molecular sieves. The theoretical value of 1:2 was not obtained in either case. Presently, we do not have an explanation for the conflicting data.

    • note
    • 2 (recrystallized from toluene) in DMSO results in rapid disproportionation. In contrast, if hydrogen peroxide is added to a suspension of palladium black obtained from a completed catalytic reaction, disproportionation is slow. These observations suggest that the Pd-catalyzed disproportionation mechanism may proceed via a Pd(II)/Pd(IV) cycle.
