Heterogeneous Palladium Catalyst

Pyridinyl functionalized MCM-48-supported Pd-catalyst efficiently (0.013–0.025 mol%) promoted Heck, Suzuki and Sonogashira cross-coupling reactions. Moreover, the catalyst was reused five times without significant loss of its activity.

Abstract An automated continuous-flow procedure has been developed for the rapid determination of urinary proteins of plasma origin. Antiserum to whole human plasma was used as the reagent, and the antigen—antibody reactions were quantitated by nephelometry. By adding polyethylene glycol (mol wt 6000-7500) to the reaction medium, reaction time was decreased to <3 min; no sample blanks were required; and samples were analyzed at a rate of 70 per hour. Recovery studies yielded an average of 98.5% of the added protein. In-run replicate precision (CV) of the method was 1.45%; day-to-day precision was 2.58%.

Considerable advances have been made using continuous flow chemistry as an enabling tool in organic synthesis. Consequently, the number of articles reporting continuous flow methods has increased significantly in recent years. This review covers the progress achieved in homogeneous palladium catalysis using continuous flow conditions over the last five years, including C–C/C–N cross-coupling reactions, carbonylations and reductive/oxidative transformations.1 Introduction2 C–C Cross-Coupling Reactions3 C–N Coupling Reactions4 Carbonylation Reactions5 Miscellaneous Reactions6 Key to Schematic Symbols7 Conclusion
