- 中文摘要: The P-phenylpropa-1,2-dienyl phosphinic amides 4a-h, the corresponding phosphinates 4i-k and the (1-phenylpropa-1,2-dienyl) phosphonic diamide 4l, whose amide N-atoms resp. ester O-atoms wear unsubstituted or substituted benzene nuclei, were formed by [2,3] sigmatropic rearrangement of the corresponding (2-alkynyloxy)phosphine derivatives 3a-l. Heating the solutions of 4a-l led in some cases to decomposition (see 4a-c), but in other cases to the tricycles 5d-l, which were formed by Intramolecular Diels-Alder (IMDA) reaction between the second allenic double bond as dienophile and the benzenic p-system as diene.
