项目摘要
Syntheses and reactivities of thiophenetriptycenesulfenic (Thtrip-SOH) and selenenic acids (Thtrip-SeOH) and triptycneneselenenic acid (Trip-SeOH) were investigated.1. Attempted synthesis of Thtrip-SeOH The oxidation of Thtrip-Se-n-Bu with dimethyldioxirane (DMD) gave the corresponding selenoxide [Thtrip-Se(O)-n-Bu] . The thermal beta-elimination of the selenoxide yielded Thtrip-Se(O)Se-Thtrip, instead of the desired selenenic acid (ThtripSeOH). Thtrip-Se(O)Se-Thtrip is the first isolable selenoseleninates and the structure was determined by X-ray crystallography.2. Synthesis of Trip-SeOH The oxidation of Trip-Se-n-Bu with DMD gave the corresponding selenoxide [Trip-Se(O)-n-Bu], the beta-elimination of which yielded the desired Trip-SeOH in a good yield. Trip-SeOH is the first isolable alkancselenenic acid and the structure was determined by X-ray crystallography.3. Reactions of Trip-SeOH Heating a solution of Trip-SeOH in dichloromethane yielded the selenoseleninate, Trip-Se(O)Se-Trip. The dimerization was not accelerated by an acid. The treatment of Trip-Se(O)Se-Trip with Et^c_3N furnished a mixture of TripSe(O)SeTrip, Trip-SeSe-Trip, and Trip-SeO_2HEt_3N, the molar ratio of which was 1 : 1 : 1. Acid-catalized hydrolysis of TripSe(O)SeTrip gave TripSeOH quantitatively.
研究了噻吩三苯磺酸(THTriP-SOH)、亚硒酸(THTriP-SeOH)和三苯基三烯硒酸(TRIP-SeOH)的合成及其反应活性。用二甲基二氧六环(DMD)氧化ThTrip-Se-n-Bu得到相应的氧化硒[ThTrip-Se(O)-n-Bu]。氧化硒的热β消除生成了ThTrip-Se(O)Se-ThTrip,而不是所需的亚硒酸(ThtripSeOH)。结果表明:1.ThTriP-Se(O)Se-ThTrip是第一个可分离的硒硒化合物,其结构经X-射线晶体分析确定。TRIP-Se-n-Bu的合成用DMD氧化TRIP-Se-n-Bu得到了相应的氧化硒[TRIP-Se(O)-n-Bu],其β消除反应以较高的产率得到了所需的TRIP-SeOH。TRIP-Seoh是第一个分离得到的烷基硒酸,其结构经X-射线衍射法确证。TRIP-SeOH加热TRIP-SeOH在二氯甲烷中的溶液的反应生成亚硒酸酯TRIP-Se(O)Se-TRIP。酸不能加速二聚反应。用Et、C_3N处理TripSe(O)Se-Trip得到了TripSe(O)SeTrip、Trip-Sese-Trip和Trip-SeO_2HEt_3N的混合物,摩尔比为1:1:1。
