Iridium-catalyzed dehydrogenation of substituted amine boranes: kinetics, thermodynamics, and implications for hydrogen storage.
Dehydrogenation of amine boranes is catalyzed efficiently by the iridium pincer complex (kappa (3)-1,3-(OP ( t )Bu 2) 2C 6H 3)Ir(H) 2 ( 1). With CH 3NH 2BH 3 (MeAB) and with AB/MeAB mixtures (AB = NH 3BH 3), the rapid release of 1 equiv of H 2 is observed to yield soluble oligomeric products at rates similar to those previously reported for the dehydrogenation of AB catalyzed by 1. Delta H for ...
متن کاملTransfer Hydrogenation Employing Ethylene Diamine Bisborane in Water and Pd- and Ru-Nanoparticles in Ionic Liquids.
Herein we demonstrate the use of ethylenediamine bisborane (EDAB) as a suitable hydrogen source for transfer hydrogenation reactions on C-C double bonds mediated by metal nanoparticles. Moreover, EDAB also acts as a reducing agent for carbonyl functionalities in water under metal-free conditions.
متن کاملDehydrogenation of amine-boranes with a frustrated Lewis pair.
Bulky tertiary phosphine/borane Lewis pairs P(t)Bu(3)/B(C(6)F(5))(3) react with amine-boranes to afford dehydrocoupling products and phosphonium borohydride salts.
متن کاملLithium Dihydropyridine Dehydrogenation Catalysis: A Group 1 Approach to the Cyclization of Diamine Boranes
In reactions restricted previously to a ruthenium catalyst, a 1-lithium-2-alkyl-1,2-dihydropyridine complex is shown to be a competitive alternative dehydrogenation catalyst for the transformation of diamine boranes into cyclic 1,3,2-diazaborolidines, which can in turn be smoothly arylated in good yields. This study established the conditions and solvent dependence of the catalysis through NMR ...
متن کاملVariable coordination modes and catalytic dehydrogenation of B-phenyl amine-boranes.
The chemistry of N-substituted amine-boranes and their reactivity towards transition metal centres is well established but the chemistry of B-substituted amine-boranes is not. Here we present the coordination chemistry of H2PhB·NMe3 towards a range of Rh(i) fragments with different P-Rh-P ligand bite angles, {Rh(P(i)Pr3)2}(+), {Rh(P(i)Bu3)2}(+), {Rh((i)Pr2P(CH2)3P(i)Pr2)}(+), {Rh(Ph2P(CH2)nPPh2...
