Abstract

New bis-crown ether containing siloxane chain was synthesized. 1,3-Bis(trimethylsiloxy)-1,3-dimethyl-1,3-di(4'-ethylbenzo-18-crown-6) disiloxane (1) was synthesized by reaction of 4'-vinylbenzo-18-crown-6 with 1,3-bis(trimethylsiloxy)-1,3-dimethyl-1,3-disiloxane in the presence of Pt catalyst. 4'-Vinylbenzo-18-crown-6 was prepared through five-step reaction which started from the reaction of catechol and acetic anhydride.

실옥산 사슬에 크라운 에테르가 연결된 유연성이 큰 새로운 비스-크라운 에테르를 합성하였다. 1, 3-Bis(trimethylsiloxy)-1, 3-dimethyl-1, 3-di(4'-ethylbenz-o-18-crown-6) disiloxane(1)은 백금촉매 존재하에서 1, 3-bis(trimethylsiloxy)-1, 3-dimethyl-1, 3-disiloxane과 4'-vinylbenzo-18-crown-6의 반응에 의해 합성하였다.
