资源简介：
Oxidative
addition of very robust C–F and C–O bonds
has been accomplished in reactions of the aluminum(I) compound NacNacAl
(1, NacNac = [ArNC(Me)CHC(Me)NAr]− and
Ar = 2,6-Pri2C6H3) with
fluoroarenes, fluoroalkanes, and ethers. Similar to the transition
metals, the ease of aryl C–F oxidative addition decreases as
the degree of fluorination diminishes on the aromatic substrate. As
well, kinetic studies on the addition of 1,2,3,4-tetrafluorobenzene
to compound 1 revealed a second-order reaction characterized
by a very negative entropy of activation (ΔS⧧ = −113.6(3) J/K·mol), consistent
with a transition metal-like oxidative addition process.
