Abstract

Rasta resin-TBD has been synthesized and used to catalyze a wide range of transesterification reactions, including biodiesel synthesis and ring-opening polymerizations. It was found to be a more efficient heterogeneous catalyst than a related polystyrene-based analogue based on the Merrifield resin architecture involving divinylbenzene cross-linking. In the reactions studied rasta resin-TBD was separated from the desired products simply by filtration, and it could be regenerated and reused numerous times without significant loss of catalytic activity.

Key words

polymer-supported catalyst - transesterification - rasta resin - organocatalysis - biodiesel

  • 11 General Procedure for the Transesterification of 17: Sunflower oil 17 (0.500 g, 0.59 mmol), MeOH (2.0 mL), and 1 (0.095 g, 0.24 mmol) were added to a 7-mL vial equipped with a magnetic stirrer. The reaction mixture was vigorously stirred at r.t. (20–22 °C) for 24 h. The reaction mixture was then poured onto a Büchner funnel and the filtrate was concentrated under reduced pressure and analyzed by 1H NMR spectroscopy. The integrated area of methoxy groups in the FAME 18 (3.67 ppm, singlet) and that of the methylene protons adjacent to the carbonyl groups present in the triglycerides (2.29 ppm, triplet) of 17 were used to calculate conversion. The beads collected on Büchner funnel were washed with hexanes (10 mL) and then dried under vacuum. Recovered 1 (0.095 g), MeOH (2 mL), and aq 0.5 M NaOH (2 mL) were added to a 7-mL vial equipped with a magnetic stirrer. The mixture was stirred slowly for 24 h and then poured onto a Büchner funnel. The beads collected on funnel were washed with H2O (10 mL), MeOH (10 mL), THF (5 mL), Et2O (5 mL), hexanes (5 mL) and then dried to constant weight under vacuum.

  • 14 General Procedure for the Reaction of Various Alcohols with Vinyl Acetate: Alcohol 24 (1.0 mmol), vinyl acetate (25; 0.103 g, 1.20 mmol), 1 (0.080 g, 0.10 mmol), and THF (1.0 mL) were added to a 3-mL vial. The vial was immersed in an oil bath regulated at 60 °C for 16 h. The reaction mixture was then cooled to r.t. and filtered. The beads collected on funnel were further washed with THF (5 mL) and the combined filtrate was concentrated under reduced pressure. The residue of concentrated filtrate afforded essentially pure products as analyzed by 1H NMR and 13C NMR spectroscopy for the substrates in Table 2 (entries 1–4). In cases when the reactions were incomplete under the given conditions, the products were purified using silica gel column chromatography with hexane as the eluent.
