A new route to dihydropyrene precursors, 1,3-bis(bromomethyl)-2-substituted-benzenes, has been found, which starts from the readily available hexachlorocyclopentadiene and 3-substituted acrylic esters. Utilization of an intermediate in this sequence, 1,3-bis(bromomethyl)-4,5-dichlorotoluenc, has opened up a route to the relatively inaccessible cis-dimethyldihydropyrenes to allow study of their chemistry
已经发现了一种新的二氢py前体1,3-双(溴甲基)-2-取代的苯的途径,它是从容易获得的六氯环戊二烯和3-取代的丙烯酸酯开始的。利用该顺序的中间体1,3-双(溴甲基)-4,5-二氯甲苯,开辟了一条通往相对难以接近的顺式-二甲基二氢吡啶的途径,以研究其化学性质。
