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.

A method for iron-catalyzed deprotonative alkylation of arene C−H bonds by alkyl iodides and bromides has been developed. In the presence of an amide base, both primary and secondary alkyl halides can be coupled with furans, thiophenes, pyridine derivatives, and some electron-withdrawing-group containing arenes.
