2-pyridinealdoxime-based Pd(II)-complex covalently anchored via the oxime moiety to a glass/polymer composite material was evaluated in Suzuki–Miyaura cross-coupling reactions of aryl and heteroaryl halides, including arylchlorides, with aryl and heteroaryl boronic acids both under thermal as well as microwaveirradiatingconditions in water. The stability and reusability of this Pd-precatalyst is part

General continuous-flow conditions for the Suzuki–Miyauracross-coupling of heteroaryl halides and (hetero)arylboronicacids have been developed. A wide range of heterobiaryl products is obtained in excellent yields (20 examples) employing low catalyst loadings (0.05–1.5 mol % Pd).

(PDGF-RTK) activity. The compounds were generally prepared either by a Friedlander condensation between an aryl-acetaldehyde and an o-aminobenzaldehyde or by a palladium-catalyzedcoupling between an aryl bromide or triflate and an organostannane or organozinc chloride. The presence of 6,7-dimethoxy groups on the quinoline ring was found to be advantageous although not essential for potent inhibition

The use of micellar conditions to enable one-pot reactions involving both transition metal and enzymatic catalysts is reported. Representative enzymatic transformations under micellar conditions are unaffected by the presence of non-ionic surfactants, including designer surfactants such as TPGS-750-M. Furthermore, the presence of enzymes has a negligible effect on transition metal catalysis under micellar
