资源简介：
Systems of the type [(p-cym)Ru(PR3)(H)(H2BNiPr2)]+ (R = Cy, Ph) can be synthesized
from (p-cym)Ru(PR3)Cl2 and
H2BNiPr2/Na[BArf4] and are best formulated as
(hydrido)ruthenium κ1-aminoborane complexes. VT-NMR
measurements have been used to probe
the σ-bond metathesis process leading to Ru–H/H–B
exchange, yielding an activation barrier of ΔG⧧ = 7.5 kcal mol–1 at 161 K. Moreover, in contrast to the case for related non-hydride-containing
systems, reactivity toward alkenes constitutes a viable route to a
metal borylene complex via sacrificial hydrogenation.
