Strained hydrocarbons from cyclic diynes: preparation and reactivity
The reaction of cyclic diynes with either CpCo(CO)2 or AlCl3 yielded strained hydrocarbons in which a Dewar benzene or a tricyclo[4.2.0.02,5]octa-3,7-diene frame is bridged by hydrocarbon chains. The photochemistry and thermochemistry of these species are discussed. Results of quantum chemical calcu...

| Zusammenfassung: | The reaction of cyclic diynes with either CpCo(CO)2 or AlCl3 yielded strained hydrocarbons in which a Dewar benzene or a tricyclo[4.2.0.02,5]octa-3,7-diene frame is bridged by hydrocarbon chains. The photochemistry and thermochemistry of these species are discussed. Results of quantum chemical calculations (DFT, CASPT2) are used to discuss the thermochemistry of four different fourfold bridged tricyclo[4.2.0.02,5]octa-3,7-dienes. Depending on the bridging mode, either a Cope-type rearrangement or a ring opening reaction is preferred. Copyright © 2002 John Wiley & Sons, Ltd. |
