Abstract
Abstract 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[3.1.0.0 2,6 ]-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.
