The synthesis and characterization of organyl complexes derived from group 4 metal dicyclohexylamido complexes (Cy 2 N) 3 MCl (Cy: Cyclohexyl, M = Ti, Zr, Hf 1‐M ) is presented. The allyl Grignard reagent is used to obtain the corresponding group 4 allyl complexes 2‐M , and lithium phenylacetylide is used to obtain the phenylacetylide complexes 3‐M . The thermal stability of complexes 2‐M and 3‐M is investigated. All complexes are characterized by NMR spectroscopy and single‐crystal X‐ray diffraction. Their molecular structures in solution and in the solid state are discussed.
