Title: (Z)-Diiodo(2-iodo-2-phenylvinyl)(phenyl)tellurium PhIC=CHTeI2Ph: Synthesis and Complexing Properties in a Reaction with Iron Pentacarbonyl
Author: TORUBAEV, YV; PASYNSKII, AA; MATHUR, P
Abstract: Electrophilic addition of PhTeI3 to phenylacetylene (PhC2H) in boiling THF stereoselectively gave (Z)-diiodo(2-iodo-2-phenylvinyl)(phenyl)tellurium PhIC=CHTeI2Ph (I). In a reaction with Fe(CO)(5), this complex easily eliminated two iodine atoms from tellurium to give PhTe-CH=CPhI. This ligand was coordinated to iron in a monodentate fashion through the Te atom in the resulting complex (CO)(3)FeI2(PhTeHC=CPhI) (II). The reaction also yielded the known complex Fe(CO)(4)I-2 (III). The structures of complexes I-III were determined by X-ray diffraction analysis. The Fe-Te bond in structure II is substantially shortened.
