Transmetallation of Mercurated N-(substituted benzyl) arylamines

A series of new asymmetric diaryltellurium dichlorides were synthesized by mercurated N-(substituted benzyl) arylamines with 4-ethoxyphenyltellurium trichloride.All the asymmetric diaryltellurium dichlorides prepared were characterized by IR,~(1)H NMR,elemental analysis.The crystal structure of compound 3c was characterized by X-ray crystal diffraction.The compounds crystalizes in monoclinic,space group P21/n with a=1.407 0(3) nm,b=0.764 59(15) nm,c=2.017 0(4) nm,α=90°,β=90.27(3)°,γ=90°,V=2.169 8(7) nm~(3),Z=4,Dc=1.579 Mg/m~(3),F(000)=(1 024),R=0.028 7,wR=0.058 0.In compound 3c,the N-Te distance of 0.308 0 nm is shorter than the sum of the van der Waals radii of Te and N(about 0.37 nm),indicating the substantial secondary intramolecular coordination between Te and N.
