I only pointed out the incorrectness of your assumption using available NMR analysis, which maybe edited appropriately. As a valuable resource, you can just read about how NMR points at aromaticity and alkene nature, that will also be beneficial to point out the inaccuracy without computational/Lab analysis. | |

Unfortunately, I am currently short of such resources as you state and if a substantial proof can be given, I would be more than happy to upvote it. I stated It would be more prevalent as similar to cyclobutadiene it seems to behave more as an intermediate than be present as a compound. And so assumed it would be more antiaromatic than aromatic. There may be flaws centered around my lack of complete knowledge, so as I said above please formulate your answer. Thanks for your concern regarding my ans. | |

The NMR calculations referred in the book shows the alkene like character at cyclobutadiene promoting Diels Alder. You've manipulated the statements well. FYI, Cyclobutadiene can be NON aromatic as well depending on the adopted geometry. As a member of 21st century you may perform the calculations yourself at any chem-computer and find the aromaticity of phenyl ring and alkene-city of cyclobutadiene | |
