Tert-butylborane: A bis (σ-B–H) ligand in ruthenium hydride chemistry
摘要:
The reaction of tert-butylborane with the bis(dihydrogen) complex RuH2(eta(2)-H-2)(2)(PCy3)(2) leads to the corresponding bis sigma-borane complex which is the first example of a monoalkylborane ruthenium bis sigma-complex. An alternative route involves the reaction of RuHCl(eta(2)-H-2)(PCy3)(2) with lithium tert-butylborohydride. (C) 2009 Elsevier B.V. All rights reserved.
