Özet
Bu çalışmada; yedi üyeli gerilimli simetrik benzoanule halkalı allen sentezi veyakalanması üzerinde çalışıldı.Yedi üyeli gerilimli ve simetrik benzoanule halkalı allen sentezi için naftalindençıkılarak 1,4-dihidronaftalin Birch reaksiyonuyla sentezlendi. Bu çıkış bileşiğinebromoflorokarben katılarak 7,7-bromofloro-3,4-benzosiklo [4.1.0]-3-heptensentezlendi. Elde edilen bu bileşik azot atmosferinde metillityum ile muameleedilerek allen dimer ürünleri izole edilerek reaktivitesi ve reaksiyonları incelendi.
In this work; synthesis and trapping seven membered strained symmetricalbenzoanule allene was worked on.At first step,1,4-dihydronaphthalene was synthesized from naphthalene by theway of birch reaction. And then 7,7-bromofluoro-3,4-benzocyclo [4.1.0]-3-heptene wassynthesized by adding fluorobromocarbene into 1,4-dihydronaphthalene.As a result, 7,7-bromofluoro-3,4-benzocyclo [4.1.0]-3-heptene was synthesizedby methylithium in the atmosphere of nitrojen. After seperation, dimer product wasobtained by coloum chromatography. Structure was elucided by spectroscopictechniques ( 1H-NMR, 13C-NMR, Mass, FT-IR).
