1,2,3,4-Tetra-t-butylnaphthalene (2), a highly crowded naphthalene derivative, has been synthesized. Upon irradiation, 2 underwent photovalence isomerization to afford 1,2,5,6-tetra-t-butyl-3,4-benzo-3-tricyclo[3.1.0.02,6]-hexene (3). The synthesis of 1,4,5,6-tetra-t-butyl-2,3-benzo-2,5-bicyclo[2.2.0]hexadiene (1), which was used for the synthesis of 2, is also described.
已经合成了高度拥挤的1,2,3,4-四叔丁基萘(2)。照射后,2进行光价异构化,得到1,2,5,6-四叔丁基-3,4-苯并-3-三环[3.1.0.0 2,6 ] -己烯(3)。1,4,5,6-四叔丁基-2,3-苯并-2,5-双环[2.2.0]己二烯(合成1),其用于合成2,还描述了。
