The Mn(III)-based oxidation of 2,7-, 1,8-, and 1,5-disubstituted naphthalenes bearing both the 1,4-dioxa-7,7-diphenylhep-6-enyl and 1,4-dioxa-5,7-dioxooctyl groups gave new [12]naphthalenophanes along with the corresponding diploids via assembly of the dihydrofuran ring. A similar reaction of the 2,6-disubstituted naphthalene having the same substituents did not produce the naphthalenophane, but the
2,7-,1,8-和1,5-二取代的萘的Mn(III)基氧化,同时带有1,4-二氧杂-7,7-二苯基庚-6-烯基和1,4-二氧杂萘-5,7-二氧辛基基团通过二氢呋喃环的组装产生了新的[12]萘二酚以及相应的二倍体。具有相同取代基的2,6-二取代萘的相似反应没有产生萘酚,但是少量获得了二倍体[12,12](2,6)萘酚。拴系在1,4,7-三氧杂-10,10-二苯基癸-9-烯基和1,4,7-三氧杂-8,10-二氧杂癸基上的2,6-二取代的萘也经历了二氢呋喃截留反应提供痕量的所需[18](2,6)萘酞菁。描述了反应的细节和产物的结构确定。
