A series of naphthalene, indene, and 6aH-benzo[c]fluorene derivatives are synthesized by intramolecular rearrangement of vinylidenecyclopropanes using a heterogeneous solid acid catalyst, montmorillonite K-10, under mild reaction conditions in good to excellent yields. The solid acidic catalyst, montmorillonite K-10, can be recovered and reused.
在温和的反应条件下,采用多相固体酸催化剂蒙脱石K-10,通过亚乙烯基环丙烷的分子内重排反应,以良好的收率获得了一系列的萘,茚和6a H-苯并[ c ]芴衍生物。固体酸性催化剂蒙脱石K-10可回收再利用。
