摘要：

In a highly selective reaction the spirocyclotrimer 2 is formed when the phosphaalkyne 1 is treated with the Lewis acid AlCl3. The diphosphet is released when dimethyl sulfoxide (DMSO) is added, and it subsequently rearranges to 1,3,5-triphospha Dewar benzene by cleavage of the P-P bond in the diphosphirene unit. This can be trapped with 1 by a homo-Diels-Alder reaction leading to the formation of the tetraphosphacubane 3. All these reaction steps are novel.
