Photochemical Reactions of Transition Metal Organyl Complexes with Olefins, 13 12. Mitteilung: Lit. . – Photochemically Induced [5+2], homo [5+2] Cycloaddition of 3‐Hexyne to Tricarbonyl(η 5 ‐2,4‐cycloheptadien‐1‐yl)manganese Tricarbonyl(η 5 ‐2,4‐cycloheptadien‐1‐yl)manganese ( 1 ) reacts upon UV irradiation in hexane at 243 K with two equivalents of 3‐hexyne ( 2 ) in successive [5+2], homo [5+2] cycloadditions to give tricarbonyl(η 2:2:1 ‐1,2,3,11‐tetraethyltricyclo‐[5.3.1.0 4,10 ]undeca‐2,5‐dien‐11‐yl)manganese ( 3 ). Its crystal and molecular structure was determined by an X‐ray diffraction analysis, in solution it was studied also by IR and NMR spectroscopy.
