Abstract

The dehydrative allylation from allyl alcohol with amines to generate various allyl amines by MoO3/TiO2 solid catalyst is described. The catalyst can be reused at least three times without a decrease of activity.

  • 15 Solid 10 wt%MoO3/TiO2 Catalyst – Typical Preparation for Heterogeneous Catalyst 22 TiO2 P25 (2.00 g) was added to a (NH4)6Mo7O24(H2O)4 (245.3 mg, 0.2 mmol) aqueous solution (1 mL), and the mixed catalyst was dried at 110 °C for 24 h, then calcined at 500 °C for 3 h under air; yield 2.20 g.
  • 16 Dehydrative Allylation of 1 with 2 – Typical Dehydrative Allylation Procedure for Screening of Solid Catalyst A pressure-resistant glass tube equipped with a magnetic stirring bar was loaded with solid catalyst (100 mg), 1 (230 mg, 4.0 mmol), 2 (197 mg, 1.0 mmol), and n-octane (0.25 mL). The vessel was tightly sealed by a screw cap, and the mixture was stirred (500 rpm) in an oil bath maintained at 105 °C for 6 h. After the reaction, the solution was cooled to room temperature and then diluted with 12 mL of acetonitrile. Biphenyl (40 mg, 0.25 mmol) was added to the solution as an internal standard for gas chromatography (GC) analysis. The solution was placed under ultrasonic irradiation for 10 min to ensure a good homogeneity of the mixture. The conversion and yield were determined on the basis of the analysis of the mixture by GC to evaluate catalytic activities. Characterization of 3 was done by 1H NMR and 13C NMR spectra. Characterization details are shown in ref. 16.

  • 19 Allyl Dibenzyl Amine (3) – Typical Dehydrative Allylation Procedure A pressure-resistant glass tube equipped with a magnetic stirring bar was loaded with MoO3/TiO2 (100 mg), 1 (240 mg, 4.1 mmol), 2 (197 mg, 1.0 mmol), and n-octane (0.25 mL). The vessel was tightly sealed by a screw cap, and the mixture was stirred (500 rpm) in an oil bath maintained at 105 °C for 6 h. The resulting mixture was concentrated and purified by column chromatography (silica gel (100–200 mesh), eluent; n-hexane/ethyl acetate = 50:1) to give a colorless oil; yield: 215 mg (94% isolated yield).
