Note : Synthesis and Characteristics of 2,6-disubstituted Pyrylium Fluoroborates

Sung Il Cho

Abstract

Pyrylium fluoroborates undergo a wide range of synthetically useful reactions because of the positive charge. And the electron accepting nature has resulted in their widespread use as sensitizers for photo-induced electron transfer (PET) reactions. In this experiment, 2,6-disubstituted pyrylium fluoroborates are synthesized from the reaction between 3'-chloroacetophenone and excess orthoformate in an acidic medium (acetic anhydride/acid). Synthesized products are confirmed by 1H-NMR, FT-IR and TOF Mass spectroscopies. Also, photo-properties are analyzed with an UV-Vis spectrophotometer.

초록

Pyrylium염 화합물은 양전하를 띄고 있어 유용한 합성반응에 널리 이용되고 있다. 또한 전자를 받아들이는 특성을 갖고 있어 광유도전자전이(PET) 반응의 감광제 등에 응용되고 있다. 우리는 본 연구에서 몇몇 2,6-disubstituted pyrylium fluoroborate 염 화합물을 산성 매체(acetic anhydride/acid) 하에서 합성하였다. 합성한 화합물을 1H-NMR, FT-IR과 TOF Mass로 그 구조를 확인하였다. 또한, 그 광특성을 UV-Vis를 통해 분석하였다.
