在苯乙烯系中,苯乙烯負离子基极易聚合,一般得单峯的波譜,只有快速測定时方得四綫譜。反式-二苯乙烯負离子基的波譜有两种报导。一种为在其所著书中提出的三組多綫譜,而另一种为最近裘祖文等发表的多重线波譜。四苯乙烯曾由Whiffen等用金属鈉制成砖紅色負离子基溶液,但未获得順磁共振信号。当时他們认为四苯乙烯負离子基是双价的,呈反磁性。除苯乙烯和反式-二苯乙烯外,我們用裘祖文的方法(鉀鏡还原法)制成三苯乙烯及四苯乙烯二
In styrenics, styrenic anion base is very easy to polymerize, generally have a single peak spectrum, only the rapid determination of quadrilateral spectrum. There are two reports of the trans-stilbene anion spectrum. One is the three sets of multi-line spectra proposed in his book, and the other is the multi-line spectrum recently published by Juzu Wen et al. Tetraphenylethylene was made by a metal-based sodium salt Whittle and other red base solution, but did not obtain the paramagnetic resonance signal. At that time they believed tetrantilide anion base is bivalent, was diamagnetic. In addition to styrene and trans-stilbene, we use the method of Chouzu (potassium reduction method) made of tristyrene and tetraphenylene two
