Abstract

The reaction of tris(3-iodopentane-2,4-dionato)cobalt(III) with vinylferrocene in the presence of triphenylphosphine and a catalytic amount of PdII produced two structural isomers. The characterisation of these isomers, 2- and 3-ferrocenyl-4-acetyl-2,3-dihydro-5-methylfuran [(B) and (C), respectively] is described. Their structures have been determined by single-crystal X-ray diffractometry: (B) is orthorhombic, space group Pbca with a = 9.821 (2), b = 10.414(4), c = 27.761(6) Å, final R = 0.031, R′ = 0.050 for 1 706 reflections; (C) is monoclinic, space group P21/c with a = 9.692(1), b = 7.678(5), c = 19.082(3) Å, β = 97.76(1)°, final R = 0.031, R′ = 0.048 for 1 641 reflections.
