摘要: Abstract Conjugated dienes, e.g. 1,3-butadiene or trans , -2,4-hexadiene, undergo [4 s + 6 ] cycloaddition with tricarbonyl-η-1,3,5-cycloheptatrienechromium(0) (I) on irradiation UV light in n-pentane at 263 K, and the bright red tricarbonyl-η-bicyclo[4.4.1]undeca-1,3,7-trienechromium(O) complexes Cr(CO) 3 C 11 H 14 (II) 13 18 (III) are formed high yields. The structures of II III were determined by IR, NMR mass spectra confirmed an X-ray structure analysis for III.
