主要报道了三苯基硼引发的2-烷基取代苯酚双锂盐的自由基偶联反应,生成了硼取代的对二苯醌化合物。有机硼化合物被认为参加自由基反应,以有机硼化合物作为自由基引发剂,并应用于芳烃化合物。我们发现当三苯基硼与2-烷基取代苯酚的双锂盐反应时,促进2-烷基取代苯酚的自由基偶联,生成了一种新型的对二苯醌衍生物,是一种收率较高的对二苯醌衍生物新型制备方法。产物的结构经元素分析、红外光谱和X-射线单晶衍射确定。
It is reported that the radical coupling reaction of triphenylboron-induced 2-alkyl-substituted phenol bis-lithium salt leads to the formation of boron-substituted p-diphenoquinone compounds. Organoboron compounds are thought to participate in free radical reactions, organoboron compounds as free radical initiators, and are used in aromatic compounds. We have found that when triphenylboron is reacted with a di-lithium salt of a 2-alkyl-substituted phenol, radical coupling of the 2-alkyl-substituted phenol is promoted to produce a novel p-diphenoquinone derivative which is a High yield of p-diphenoquinone derivatives a new method of preparation. The structure of the product was confirmed by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction.
