polyunsaturated ketones and hydrocarbons 1–5 for which NMR, IR and UV spectra at low temperature are reported. The Diels—Alder adducts of compounds 1–3 with various dienes, the 1,6 additions of several nucleophilic agents with 4, and the isomerisation of 5 in p-ethynylstyrene support the proposed structures.
通过快速热解双Diels-Alder逆向裂解,得到了新的,不稳定的多不饱和酮和碳氢化合物1-5,据报道,它们在低温下具有NMR,IR和UV光谱。化合物1-3与各种二烯的Diels-Alder加合物,几种亲核试剂与1,4的1,6加成以及对乙炔基苯乙烯中5的异构化均支持所提出的结构。
