| Abstract: | Reaction of indene, 1,1-dimethylindene, spirocyclopropane-1,1-indene, and spirocyclopropane-9,9-fluorene with Py3M(CO)3/BF3 · OEt2 (M = Cr, Mo, W) involves two competing processes: (i) the formation of the 6-arene complexes (A) and (ii) the oxidative addition at the C(1)R and C(9)R bonds (R = alkyl) with the formation of chelated σ,π-complex (B). The reaction pathway (A or B) is determined both by the metal and the ligand. |
