| Photoreaktionen von Dekacarbonyldirhenium mit A llen und unverzweigten Allenderivaten Photoreactions of Decacarbonyldirhenium with Allene and Unbranched Derivatives o f Allene  | | | Abstract
| Decacarbonyldirhenium (1) reacts upon U V irradiation with allene (2), 1,2-butadiene (3) and 2,3-pentadiene (4) preferentially by CO substitution and oxidative rearrangement to the corresponding enneacarbonyl-//-?/1:3-endiyl-dirhenium complexes 5, 9, and 15 and to the octacarbonyl-,«-//-:2-allene-dirhenium complexes 6, the stereoisomers 10, 11, and 16. A t ele vated temperature 5, 9, and 15 loose CO and yield by a reductive rearrangement also the complexes 6, 10, 11, and 16. In addition to these main products, depending upon the allene derivative used, various by-products are obtained. By-products of the reaction o f 1 with 2 are octacarbonyl-M-/73:3-(2,3-dimethylene-buta-l,4-diyl)dirhenium (7) and ^-^^-allene-hexacarbonyl-/!-//1:3-i-propene-l,3-diyl-dirheniurn (8). The photo reaction of 1 with 3 yields, in addition to 9-11 , tetracarbonyl-^3-(£'-5-ethylidene-4-methyl-2-cyclopenten-l-yl)rhenium (12) | | |
