The generation of the new functionalized and highly pyramidalized alkenes, 3,7-(2,2‘-biphenylene)tricyclo[3.3.0.03,7]oct-1(5)-ene (20) and 3,7-sulfonyldioxytricyclo[3.3.0.03,7]oct-1(5)-ene (39), and their trapping with 1,3-diphenylisobenzofuran and 11,12-dimethylene-9,10-dihydro-9,10-ethanoanthracene are described. While both alkenes 20 and 39 failed to give the expected cyclobutane or diene dimers
新型官能化和高度金字塔化的烯烃3,7-(2,2'-联苯)三环[3.3.0.0 3,7 ] oct-1(5)-烯(20)和3,7-磺酰基二氧基三环[ 3.3.0.0 3,7 ] oct-1(5)-烯(39),及其被1,3-二苯基异苯并呋喃和11,12-二亚甲基-9,10-二氢-9,10-乙基蒽的捕集方法进行了描述。虽然烯烃20和39均无法提供预期的环丁烷或二烯二聚体,但20与3,7-二甲基三环[3.3.0.0 3,7 ] oct-1(5)-烯(1b)反应生成交联产品4,5-(2,2')-联苯-10,11-二甲基五环[8.2.1.1 2,5 .1 4,7.1 8,11 ]十六烷-1,7-二烯(33)。化合物20的DFT计算[B3LYP / 6-31G(d)]给出了该锥体链烯烃的重要参数,例如锥体角(61.7°),应变能(72.9 kcal / mol)和HOMO / LUMO间隙( 3.79 eV)。
