摘要

A synthesis of the parent hydrocarbon, 1-cycloheptatrienylidene-4-cyclopentadienylidene-2, 5-cyclohexadiene (4), was attempted. The approach was based on the dehydrogenation of the dihydro derivative 11. Hydride abstraction of 11 did not lead to the desired tropylium salt 13. A synthetic approach to the tetraphenyl derivative 17 involved the tropylium salt 16. Deprotonation of 16 produced an apparent oligomer of 17. A stable organoiron derivative ...
