Abstract

New complexes of transition metals with organotellurium halide ligands are reported. Iodination of [CpMn(CO)2]2(μ-Ph2Te2) leads to the Te–Te bond cleavage and formation of CpMn(CO)2(PhTeI). Oxidative addition of PhTeBr3 to Fe(CO)5 gives the monomeric complex (CO)3FeBr2(PhTeBr) which is isostructural with the recently reported (CO)3FeI2(PhTeI). Insertion of phenyltellurenyl iodide (PhTeI) into the Fe–I bond of CpFe(CO)2I forms CpFe(CO)2(TeI2Ph). Molecular structures of the reported complexes were determined by single-crystal X-ray diffraction analysis (XRD). A considerable shortening of metal–tellurium distances is observed.

Graphical abstractIodine cleaves the Te–Te bond in [CpMn(CO)2]2(μ-Ph2Te2) to give the new phenyltellurenyliodine complex CpMn(CO)2(PhTeI). Insertion of PhTeI into the Fe–I bond of CpFe(CO)2I yields CpFe(CO)2(TeI2Ph). Oxidative addition of PhTeBr3 to Fe(CO)5 gives (CO)3FeBr2(PhTeBr) and it is isostructural to the recently reported (CO)3FeI2(PhTeI). Molecular structures of the reported complexes are discussed.Figure optionsDownload full-size imageDownload as PowerPoint slide
