  Aldehyde Bis-arylation by Metal Triflates Including Bismuth Triflate Powder

  摘要：

  Development of an efficient catalytic reaction promoted by a metal triflate has been emphasized in contemporary synthesis. To evaluate the potential of some metal trflates such as bismuth triflate in our process research, we devised here an expedient protocol for its preparation and characterization. Comparison of its catalytic activity with other well-known metal triflates such as scandium triflate and copper triflate was made in a glyoxylate arylation reaction, which is a useful transformation for the construction of a 1,1-diarylethane skeleton, Furthermore, NMR analysis of Bi(OTf)(3) in acetone-d(6) revealed the unique nature and reactivity of the triflate, which has not heretofore been disclosed.

  An improved method of manufacture of a bisphenol comprises heating a monohydric phenol to a first temperature sufficient to melt the monohydric phenol; adding a carbonyl compound to 2.0-3.0 molar equivalents, based on the moles of carbonyl compound, of the monohydric phenol in the presence of catalytic amounts of an organosulfonic acid catalyst and a reaction promoter at a second temperature sufficient to maintain unreacted monohydric phenol in a molten state; increasing the temperature to a third temperature higher than the second temperature, and mixing for a time sufficient to produce the bisphenol in a yield of 80 to 100%, based on the amount of carbonyl compound; wherein mineral acids, Lewis acids, and ion exchange resins are not used. The method is applicable to the manufacture of 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane, a useful intermediate for the manufacture of bifunctional poly(phenylene ether)s.

  Disclosed herein is a method for producing a 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. The method comprises forming a reaction mixture comprising at least one substituted or unsubstituted phenolphthalein compound, at least one substituted or unsubstituted primary hydrocarbyl amine, and an acid catalyst; and heating the reaction mixture to form 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. An adduct of the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine is formed either by using an excess of the primary hydrocarbyl amine in the first heating step, or by isolating crude 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine after the heating step and then reacting with a further amount of the primary hydrocarbyl amine. The 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine has a formula: where R 1 is selected from the group consisting of a hydrogen and a hydrocarbyl group, and R 2 is selected from the group consisting of a hydrogen, a hydrocarbyl group, and a halogen.
