资源简介：
The preparation of novel phosphinite- and phosphonite-bearing
copper(I)
complexes of the general formula [CuX(L)] is reported. These compounds,
which remain scarce in the literature, could be prepared using readily
available starting materials and were spectroscopically and structurally
characterized. These complexes, together with their known phosphine
and phosphite analogues, were then applied to the 1,3-dipolar cycloaddition
of azides and alkynes, to find that the new complexes displayed the
best activities. Full optimization of the reaction conditions resulted
in a noteworthy Click catalytic system, active under very mild reaction
conditions in the absence of any additive and using low metal loadings.
