微波輔助聚合物化學(xué):Heck反應(yīng), 酯交換反應(yīng),Baeyer- Villiger氧化反應(yīng),惡唑啉(oxazoline)聚合反應(yīng),丙烯酰胺以及多孔材料聚合反應(yīng)

摘要
    若干問(wèn)題仍然開放論及微波輻射對(duì)有機(jī)和高分子化學(xué)的不同影響。因此, 對(duì)相關(guān)的調(diào)查實(shí)驗(yàn)結(jié)果進(jìn)行分析,我們闡明三個(gè)微波輻射的主要影響:有效的非接觸式加熱,加*果,以及我們專門稱的特殊效果。 
    在本文中,*: 利用HECK-縮聚反應(yīng)( HECK-POLYCONDENSATION) 以及通過(guò)微波輔助合成聚合物(2, 5-dibutoxy-1, 4-phenylenevinylene)作為一個(gè)例子證明微波的 “有效地加熱(EFFICIENT HEATING)”。第二: 通過(guò)Baeyer–Villiger 反應(yīng)合成較高內(nèi)酯的1-oxa-2-oxocyclooctanone and 1-oxa-2-oxocyclononanon作為一個(gè)例子證明微波的 “加*果(ACCELERATING EFFECT)” 。第三:我們zui近的調(diào)查工作也給予更詳細(xì)的微波效應(yīng)的解釋,并提供特殊微波效果(SPECIAL MICROWAVE EFFECT)的實(shí)例。微波合成
 

Microwave-assisted polymer chemistry: Heck-reaction,transesterification, Baeyer–Villiger oxidation, oxazoline polymerization, acrylamides, and porous materials

Abstract—Several questions are still open concerning the different effects of microwave (MW) irradiation in organic and macromolecular chemistry. Analyzing experimental results on a relatively broad investigation area, we came to elucidate three main effects of microwave irradiation: efficient non-contact heating, an accelerating effect, and what we term a special effect.
In this paper, we report the first MW assisted synthesis of poly (2, 5-dibutoxy-1, 4-phenylenevinylene) via Heck-polycondensation as an example for efficient heating. The facile synthesis of the higher lactones 1-oxa-2-oxocyclooctanone and 1-oxa-2-oxocyclononanone via Baeyer–Villiger reaction offers indeed an example for theMW-accelerating effect. A survey of our recent work is also given to explain the effects more in detail and to provide examples of the special MWeffect.
