  Electrophilic substitution of methylene-bridged polycyclic aromatic hydrocarbons

  摘要：

  The electrophilic bromination and formylation of the methylene-bridged polycyclic aromatic hydrocarbons 11H-benz[bc]aceanthrylene (2), 4H-cyclopenta[def]chrysene (3), 13H-dibenz[bc,l]aceanthrylene (4), and 4H-benzo[b]cyclopenta[mno]chrysene (5) were investigated. All reactions proceeded with high regioselectivity to afford predominantly a single major isomeric product. The sole exception was bromination of 3 which gave a small amount of a second isomeric product. The sites of electrophilic substitution were correlated with theoretical predictions from semiempirical molecular orbital calculations using the MNDO method, The observed sites of electrophilic substitution were in excellent agreement with the theoretical predictions in the cases of 2-4. However, in the case of 5, substitution took place in the 6-position, whereas the site predicted to be most reactive is the 5-position. In addition, the aryl aldehyde products were converted into the corresponding methyl derivatives for studies of their potential carcinogenicity.

  亚甲基桥接聚芳烃的合成

  摘要：

  亚甲基桥聚芳烃是一类相对少见的多环芳烃，其化学性质尚未被开发。尽管它们被怀疑是致癌的环境污染物，但这类烃很少有人知道，并且缺乏通用的合成方法。现在描述一系列亚甲基桥聚芳烃的方便合成。这些合成是基于原型烃环戊[def]菲（1），其包含预先存在的亚甲基桥。制备的聚芳烃包括13 H-二苯并[bc，l]乙炔（3），4 H-环戊[pqr] pic烯（5）4 H-苯并[b]环戊[并茂]（6），13 H-茚并[2,1,7-萘并（7）和4 H-环戊[def] dibenz [a，c]蒽（8），所有这些都是先前未知的。通过其六氢前体的催化或化学脱氢制备4 H-苯并[c]环戊五烯（4）的尝试失败。这可能是由于4的峡湾区域中的空间拥挤，以及对亚甲基桥所引起的平面性变形的抵抗力所致。诱变分析的初步发现支持以下假说，即亚甲基桥连的聚芳烃的活性诱变代谢产物是桥位上醇代谢产物的硫酸酯。

  synthetic approaches are lacking. Convenient syntheses of a series of methylene-bridge polyarenes are now described. These syntheses are based upon the prototype hydrocarbon cyclopenta[def]phenanthrene (1) which contains a pre-existing methylene bridge. Polyarenes prepared include 13H-dibenz[bc,l]aceanthrylene (3), 4H-cyclopenta[pqr]picene (5) 4H-benzo[b]cyclopenta[mno]chrysene (6), 13H-indeno[2,1,7-qra]naphthacene
