pyramidalized tricyclo[3.3.0.03,7]oct-1(5)-ene derivatives (generated from a 1,2-diiodo precursor on reaction with t-BuLi, 0.45% sodium amalgam and molten sodium) with different dienes (11,12-dimethylene-9,10-dihydro-9,10-ethanoanthracene, 1,3-diphenylisobenzofuran, 2,5-dimethylfuran and furan) is presented. Byproducts from the trapping of pentacyclo[6.4.0.02,10.03,7.04,9]dodeca-5,8,11-triene with 1,3-diphenylisobenzofuran
高度金字塔化的三环[3.3.0.0 3,7 ] oct-1(5)-烯衍生物(由1,2-二碘代前体与t -BuLi,0.45%的钠汞齐和熔融的钠反应生成的捕集剂的研究))具有不同的二烯(11,12-二亚甲基-9,10-二氢-9,10-乙基蒽,1,3-二苯基异苯并呋喃,2,5-二甲基呋喃和呋喃)。已合成并充分表征了五环[6.4.0.0 2,10 .0 3,7 .0 4,9 ] dodeca-5,8,11-三烯与1,3-二苯基异苯并呋喃的捕集副产物,包括X-射线衍射分析。此外,上述三烯已与3,7-二甲基三环[3.3.0.0 3,7] oct-1(5)烯制得四仲十二面体八烯衍生物。
