Dehydrogenation of ammonia-borane by cationic Pd(II) and Ni(II) complexes in a nitromethane medium: hydrogen release and spent fuel characterization

01.04.2015 | Sung-Kwan Kim; Sung-Ahn Hong; Ho-Jin Son; Won-Sik Han; Artur Michalak; Son-Jong Hwang; Sang Ook Kang, Dalton Transactions, 2015

A highly electrophilic cationic PdII complex, [Pd(MeCN)4][BF4]2 (1), brings about the preferential activation of the B–H bond in ammonia-borane (NH3·BH3, AB). At room temperature, the reaction between 1 in CH3NO2 and AB in tetraglyme leads to Pd nanoparticles and formation of spent fuels of the ...
