Cross-couplings of alkyl halides with heteroaromatic halides, in water at room temperature
摘要:
Zn-mediated, Pd-catalyzed cross-coupling reactions between heteroaromatic and alkyl halides can be done at room temperature in pure water using a commercially available Pd catalyst and PTS, a nanomicelle-forming amphiphile. Notably, zinc metal inserts selectively into a carbon sp(3)-halide bond, while palladium adds oxidatively to a carbon sp(2)-bond. (C) 2010 Elsevier Ltd. All rights reserved.
