资源简介：
The first reported
neutral boron(III) adducts of bis(amino)cyclopropenylidene
carbenes (BAC carbenes) have been synthesized, structurally characterized,
and applied in homogeneous reaction chemistry. These air-stable adducts
have been prepared by the combination of a BAC carbene lithium tetrafluoroborate
adduct with borane dimethyl sulfide, boron trifluoride etherate, or
dicyclohexylborane. A borenium cation derived in situ from the dicyclohexylborane
adduct catalytically reduces unhindered benzyl ketimines, a class
of substrate that cannot be reduced by prior borenium catalysts, at
room temperature, employing 20 atm of hydrogen gas as the terminal
reductant.
