A series of newionic binuclear Pd(II) complexes supported by water‐soluble bis(α‐diimine) ligands were prepared and employed as catalysts for the palladium‐catalyzed Suzuki reaction in aqueous media. The binuclear nature of the complexes increased the reaction rate, while electronic and steric modification of the ligand frameworks had a remarkable influence upon the catalytic activity of the palladium

A process for preparing vinyl esters of tertiary carboxylic acids by liquid phase addition of acetylene and tertiary carboxylic acids in the presence of metal salts of the tertiary carboxylic acids is disclosed. By subjecting the catalyst into a pre-activation and controlling the per pass conversation rate of free tertiary carboxylic acid during the reaction, the activity of catalyst, the selectivity of tertiary carboxylic acid for vinyl ester thereof, the per pass conversion rate of acetylene, and/or the selectivity of acetylene for vinyl ester of the tertiary carboxylic acid are improved.
yellow azo and blue anthraquinone chromophores, five green reactive dyes with different number of sulfonate groups were synthesized. The relationshipbetween their structures and printing properties was investigated in terms of color yield and fastness properties. The results showed the reactive dye with fewer number of sulfonate groups was more sensitive to alkaline. The color yields of dyes with
