appropriate nucleophilic group in the 1-position, or decafluorocycloheptenes with such groups in the 1,2-positions. 1-[I(CH2)3]-C7F11 was made from the analogous methoxy-compound and cyclized to the decafluorobicyclo-[5,3,0]dec-1(7)-ene. Reactions of II with NaBH4 and with LiAlH4 afforded 1H-undeca-, 1H,2H-deca- (XIII), and 1H,7H,7H-nona-fluorocycloheptene. Diels-Alder cyclo-additions of cyclopentadiene to
十二氟环庚烯(II)通过与n- BuOH / KOH,n - BuLi ,n- BuMgBr和MeO(CH 2)3 MgBr加成/消除反应,得到在1位带有适当亲核基团的十氟环庚烯或具有此类基团的十氟环庚烯在1,2位。1- [I(CH 2)3] -C 7 F 11由类似的甲氧基化合物制成,并环化为十氟双环-[5,3,0] dec-1(7)-烯。II与NaBH 4和LiAlH 4的反应得到1H-undeca-,1H,2H-deca-(XIII)和1H,7H,7H-壬基-氟环庚烯。环戊二烯的Diels-Alder环加成反应成氟代环庚烯II和XIII得到适当的三环加合物。所有产物的结构均经光谱确认。
