Notes:
Pentacarbonyl(μ-.4:6-1,4-dimethylnapthalene)dimanganese-(Mn-Mn) (1), upon UV irradiation at 193 K in the presence of 2-butyne (2), yields tetracarbonyl(μ-.2:2-2-butyne)(μ-1,2,3,4-.:1,4,4a,8a-.-1,4-dimethylnaphthalene)dimanganese (3) and tricarbonyl(4a,6,7,8,8a-.-5-hydro-1,4-dimethylnapthalene)-manganese (4). The tetracarbonyl complex 3 rearranges in solution at room temperature to give tetracarbonyl(μ-.2:2-2-butyne)(μ-4a,5,8,8a-.:5,6,7,8-.-1,4-dimethylnaphthalene)-dimanganese (5). The complexes 3 and 5 were characterised by IR and NMR spectroscopy, and by mass spectrometry, and complex 4 by IR and NMR spectroscopy. The molecular structures of 3 and 4 were determined by single-crystal X-ray diffraction analyses.
