The oxydiacetate and iminodiacetate complexes of oxidovanadium(IV) as the new series of the catalysts for the oligomerization of beta-olefin derivatives

摘要

The oxydiacetate (oda) and iminodiacetate (ida) complexes of oxidovanadium(IV) with 1,10-phenantroline (phen) and 2,2'-bipyridine (bipy) have been synthesized. The six following complexes: [VO(oda) (H2O)(2)], [VO(oda)(bipy)]center dot 2H(2)O, [VO(oda)(phen)]center dot 1.5H(2)O, [VO(ida)(H2O)]center dot H2O, [VO(ida)(bipy)]center dot 2H(2)O and [VO(ida)(phen)]center dot 2H(2)O have been used as the new catalysts for the oligomerization of 2-chloro-2-propen-1-ol. The oligomerization process undergoes very easy at room temperature and under atmospheric pressure. All products of the oligomerizations have been studied with the several analytical methods such as the matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF-MS), the nuclear magnetic resonance spectroscopy (NMR) and the thermogravimetric analysis (TGA) coupled with the analyzer of the infrared (IR) spectroscopy. The catalytic activities of the synthesized oxidovanadium(IV) complexes have been calculated which show that these complexes are the active catalysts in the 2-chloro-2-propen-1-ol oligomerization.
