Unusual rearrangements were shown to accompany Brønsted acid-assisted peri-annulations of 1-perimidines with 5-alkynylpyrimidines. These transformations take different routes depending on the nature of acetylene precursor, and lead to the formation of 7-formyl-1,3-diazopyrenes.
在 Brønsted 酸辅助的 1-脒基嘧啶与 5-炔基嘧啶的周环反应中，出现了不寻常的重排。这些转化取决于乙炔前体的性质，走不同的路线，并导致 7-甲酰基-1,3-二氮杂芘的形成。
