资源简介：
Trifluoroacetimidoyl metal complexes are useful intermediates
for
the selective synthesis of organofluorine compounds. Herein, we report
preparations, structures, and reactions of fluorinated imidoyl palladium
complexes. Oxidative addition of trifluoroacetimidoyl halides to Pd(PPh3)4 afforded quantitatively the imidoyl palladium(II)
complexes with phosphine ligands. The reaction of trifluoroacetimidoyl
iodides with Pd2(dba)3 provided the phosphine-free
imidoyl palladium complex in high yields. The X-ray crystal structure
analysis of the phosphine-free complex [Pd(μ-I){μ-C(CF3)N(PMP)}]4 revealed a cyclic tetranuclear
structure containing the imidoyl and iodo bridges. The generation
of aminotrifluoromethylcarbene equivalents by protonation or electrophilic
alkylation of imidoyl palladium(II) complexes is discussed.
