Also known as: dehydrogenative coupling - dehydropolymerization Preceded by: Wurtz-Fittig reaction , coupling of elements through the halide and not the hydride. Disadvantages : use of expensive halides, handling of alkali metals. Scope: One particular dehydrocoupling is in vogue as hydrogen storage solution: the reaction of amino borane (Denney et al. 2006 DOI) with an organoiridium pincer catalyst to an cyclic aminoborane oligomer with quantitative formation of hydrogen.
Most recently in 2008 using the same catalyst a practical synthesis was reported for linear high molar mass poly(N-methylaminoborane) (NHMeBH2)n (Staubitz et al. DOI).
