资源简介：
New fluorinated bis(pyrazolyl)methanes with the general formula RCH(PzF)2 [R = H,
PzF = 3-(trifluoromethyl)pyrazolyl, 3,5-bis(trifluoromethyl)pyrazolyl; R = Ph, PzF = 3,5-bis(trifluoromethyl)pyrazolyl] have been prepared, and their reactivity with copper and silver salts has been
studied. Copper derivatives Cu[RCH(PzF)2](L)(OTf) [R = H, PzF = 3-(trifluoromethyl)pyrazolyl,
3,5-bis(trifluoromethyl)pyrazolyl; R = Ph, PzF = 3,5-bis(trifluoromethyl)pyrazolyl, L = CO, cyclooctene
(coe); R = Ph, PzF = 3,5-bis(trifluoromethyl)pyrazolyl, L = coe, 4-vinylanisole (van), and triethylvinylsilane (tevs)] have been isolated by reacting Cu(OTf)(toluene)0.5 with the bis(pyrazolyl)methane
ligand in the presence of olefin or CO. Some of them have been structurally characterized (R = H, PzF
= 3-(trifluoromethyl)pyrazolyl, 3,5-bis(trifluoromethyl)pyrazolyl, L = CO). These compounds
are monomeric and show strong interactions between copper and one oxygen atom of the triflate
moiety. [Bis[3,5-bis(trifluoromethyl)pyrazolyl]methyl]silver complexes have been prepared from
AgBF4 and the ligand. The coe derivative [Ag{CH2(3,5-(CF3)2Pz)2}(coe)]BF4 has been obtained in good
yields.
