The synthesis and properties of electron rich olefins containing benzimidazolidine moliety

This thesis consists of three parts. In the first part; work with electron rich olefins done by previous researchers is considered. In the second part, the synthesis methods of the newly synthesised electron rich olefins and their some derivatives were given. The synthesised electron rich olefins and their derivatives in this work are shown in schemeÇHjCHjPh o> 12 R=CH,GH, A=Se CH,CH,Ph I CXJ-jr"-" 16 R=CH, CH,CH,Ph I CH,CH,Ph ai^XO^aRO 2 R=CH2CH3, R'=H, X=I 3 R=CH3, R'=H, X=l 4 R=CH2CH2Ph, R'=H, X=Br 5 R=CH2CH2OCH3, R'=H, X=Br 8 R=CH3 9 R=CH2CH2Ph' f=16. group elements, /i=PhNCS, »FPhNCO, iv=CS2, v=CH3CN PhCH2CH Ph O -cççl CH3CH/ JJ £" 17 CH,CH,Ph T 2 2 - *" +y-c=s ^A-N ı.
