Homogeneously catalysed Suzuki coupling reaction in microemulsion systems with recycling of the catalyst !"#$%& ’’ ()$)( ’’’’*’+,##)( ’’’’+’#)( ’’’’-’#! -)./’01’.101#.10123 Science is wonderfully equipped to answer the question “How?“ but it gets terribly confused when you ask the question “Why?” Erwin Chargaff Abstract The Suzuki cross coupling reaction of 2-Bromobenzonitrile and 4-Methylbenzeneboronic acid was investigated in microemulsions (heptane/water/surfactant) and catalysed by the water soluble catalyst complex Pd-TPPTS. Thereby, the formulation of microemulsions was studied under reaction conditions with the aim of enhancing the rate in comparison to a biphasic system (without surfactant). Furthermore, the use of heptane/water resulted in unselective reaction with the production of homocoupling product of arylboronic acid.
