Poly(vinylimidazolium)s from Histamine: A Recyclable Organocatalyst Precursor in the Benzoin Condensation Reaction

학위논문 (석사)-- 서울대학교 대학원 : 화학과, 2013. 8. 정영근.Poly(imidazolium)s (2) derived from 4-vinylimidazoliums (1) have been used as a precatalyst in the benzoin condensation and the formation of -butyrolactones from benzaldehydes and methyl acrylate. The poly(N-heterocyclic carbene)s (3) generated from 2 showed higher catalytic activities than those displayed by a monomeric analogue 1 and were successfully recovered and reused without loss of performance over several cycles in the benzoin condensation reaction.Abstract …3 Introduction …5 Results and Discussion …8 Conclusion …18 Experimental Section …19 References … 38 국문초록 …42Maste
