Microporous polyacetylene networks as catalysts for β–pinene oxide rearrangement – influence of catalysts and solvent type

Original language description

β-Pinene and β-pinene oxide are the important compounds for fine chemicals production. Due to their non-specific organoleptic properties, they are often transformed into the more appealing compounds such as myrtanal, myrtenol or perillyl alcohol.1 In foregoing works1,2 the influence of catalysts type (in relation to the acidity type) was studied. Using Lewis acids as catalysts the formation of myrtanal was preferred1 while using Brønsted acids the creation of perillyl alcohol was favored.2 Our previous research showed the significant influence of solvent type on the reaction course.3,4 Microporous polyacetylene networks prepared by chain growth polymerization of multifunctional alkynes (1,4-diethynylbenzene, 1,3,5-triethynylbenzene and tetrakis(4-ethynylphenyl)methane) contained terminal ethynyl function groups.5 The acid terminal hydrogen in ethynyl function group can serve as a catalytic centre for isomerization of β pinene oxide. The crucial influence of catalyst and solvent type was confirmed in this work. The best results were achieved using DMSO as a solvent and poly(1,3,5-triethynylbenzene) as the catalyst (the yield of perillyl alcohol about 50 % in 15 min). The catalyst can be simply separated from the reaction mixture and reused in the reaction with a small decrease of activity.
