• Substituted Bisphenols as Antioxidants for Autoxidation of Tetralin
  作者：Fukiko Yamada、Tomihiro Nishiyama、Masahiro Yamamoto、Kazunori Tanaka

  DOI：10.1246/bcsj.62.3603

  日期：1989.11

  The antioxidative activities of nineteen compounds of seven series of alkylidene- and benzylidenebisphenols were evaluated by means of an oxygen-absorption method at 60 °C for tetralin. The electrochemical oxidation potentials determined using linear-sweep voltammetry and the 13C NMR chemical shifts (δ) of these compounds were obtained. These data were associated with the antioxidative activities.

  采用吸氧法在 60 °C 条件下对四氢萘的抗氧化活性进行了评价，研究了 7 个系列的亚烷基和亚苄基双酚的 19 种化合物的抗氧化活性。获得了使用线性扫描伏安法测定的电化学氧化电位和这些化合物的 13 C NMR 化学位移 (δ)。这些数据与抗氧化活性有关。特别是，发现诱导期 (min) 表现出的活性与 OH 取代基的同碳的 13C 化学位移密切相关 (corr. coeff. = 0.991)。已经观察到一系列 2,2'-亚烷基-和亚苄基双（4,6-二甲基苯酚）衍生物具有非常好的活性。

  A polymeric, phosphorus-containing composition derived from aryl to aryl coupling of a substituted 2,2'-dihydroxyl-1,1'-binaphthalene or a substituted 2,2'-dihydroxyl-1,1'-biphenylene and phosphonylated at the dioxyl of said structure with at least one diaryloxyphosphite [-P(-O-Ar)2], diarylphosphine [-P(Ar)2] and/or aryl, aryloxyphosphinite [-P(Ar)(-O-Ar)], where each Ar is individually phenyl, substituted phenyl, naphthyl, and substituted naphthyl, provided that the two Ar groups that are directly or indirectly bonded to the same phosphorus atom may be linked to each other by a linking unit selected from direct bond, alkylidene, secondary or tertiary amine, oxygen, sulfide, sulfone, and sulfoxide. Polymerization by aryl to aryl coupling is achieved by direct oxidative coupling of the binaphthalene or biphenylene, copolymerization with an aromatic comonomer, or copolymerization with an aldehyde. The phosphonylation may be performed prior to or after polymerization. The polymeric, phosphorus-containing compositions in combination with a Group VIII metal and, optionally a Lewis acid, are particularly useful in the catalytic hydrocyanation of unsaturated organic compounds, isomerization of unsaturated, branched nitriles to unsaturated linear nitriles, and hydroformylation of unsaturated organic compounds.
