The reaction of nickelocene with BrMgR, where R = CH 2 CH(CH 3 )C 6 H 5 , C 2 H 5 , (CH 2 ) 7 CH 3 and CH 2 CH 2 CH 3 , have been studied. It was found that the presence of β-hydrogen in R did not cause the total splitting of the carbon-nickel bond but alkylidynetrinickel clusters were formed. It is the first example of the synthesis of alkylidynetrinickel clusters (NiCp) 3 CR from the organonickel species possessing β-hydrogen. Besides trinickel clusters, the following compounds were always formed in all the studied reactions: (NiCp) 4 H 2 , (NiCp) 6 , CpNi(η 3 -C 5 H 7 ) and (NiCp) 2 (μ-C 5 H 6 ). The structure of (NiCp) 3 CCH(CH 3 )Ph has been determined by a single-crystal X-ray diffraction study.
