The purity of reagents was in the range 97–100%.

All chemical compounds: vanadyl acetylacetonate, vanadyl sulfate pentahydrate, 1,10-phenanthroline, thiodiacetate, oxydiacetic acid, 2-phenylpyridine, dipicolinic acid, 4,4′-dimethoxy-2,2′-bipyridine, 2,2′-bipyridine, n-hexane, ethylaluminium dichloride, dimethyl sulfoxide, 3-buten-2-ol, allyl alcohol, 2-chloro-2-propen-1-ol and 2,3-dibromo-2-propen-1-ol were purchased from Merck, Darmstad, Germany. The purity of the reagents was in the range of 97–100%.

The synthesis procedure of oxovanadium(IV) microclusters with 2-phenylpyridine was as follows:
Mix vanadyl acetylacetonate VO(acac)₂ (2.65 g), H₂oda (oxydiacetic acid) (1.34 g), and 2.86 mL (0.02 mol) of 2-phenylpyridine, then add 50 mL of water. Boil everything until the solution changes color. The mixture should be refluxed at 100 °C for 2 h. After one month, a new compound was obtained in the form of crystals.
The selected olefins, 3-buten-2-ol, 2-chloro-2-propen-1-ol, allyl alcohol, and 2,3-dibromo-2-propen-1-ol (purchased from Merck), were subjected to oligomerization processes at nitrogen atmosphere, atmospheric pressure, and 65 °C. In the first step, solutions containing 3 µmol of the synthesized complex, 1 mL of toluene, and 1 mL of DMSO were prepared in a glass cell. In the next step, 3 mL of modified methylaluminoxane (MMAO-12, 7 wt.% aluminum in toluene—purchased from Merck) was slowly added into the cell. Next, 1 mL of 3-buten-2-ol, 2-chloro-2-propen-1-ol, allyl alcohol, and 2,3-dibromo-2-propen-1-ol, respectively, were added into the mixture of oxovanadium(IV) microclusters with 2-phenylpyridine activated with modified methylaluminoxane. The solution of each olefin was stirred until a gel was formed.
