Vanadium(IV) oxido complex of 1-Phenyl-1,3-butanedione [V^IVO(bzac)₂] (1) was prepared, characterized, and heterogenized onto APTMS modified graphene oxide, as well as imidazole modified polystyrene beads. Graphene oxide supported complex GO-APTMS-[V^IVO(bzac)₂] (2) and polymer anchored complex PS-im-[V^IVO(bzac)₂] (3) were used for the oxidative bromination of a number of small organic molecules and oxidation of a series of thioethers. Both 2 and 3 evolve as excellent heterogeneous catalysts. The nature of solid support does not impact substrate conversion (%) during the oxidative bromination of salicylaldehyde, phenol, or styrene, whereas it influences the substrate conversion (%) as well as the product selectivity (%) during the oxidation of thioethers.

苯甲酰丙酮钒 (IV) 氧化络合物多相催化氧化溴化和氧化硫醚及固体载体的影响

制备、表征了 1-苯基-1,3-丁二酮 [V ^IV O(bzac) ₂ ] ( 1 ) 的钒 (IV) 氧化复合物，并将其异质化到 APTMS 改性的氧化石墨烯以及咪唑改性的聚苯乙烯珠上。氧化石墨烯负载复合物GO-APTMS-[V ^IV O(bzac) ₂ ] ( 2 ) 和聚合物锚定复合物PS-im-[V ^IV O(bzac) ₂ ] ( 3 ) 被用于氧化溴化许多有机小分子和一系列硫醚的氧化。既2和3发展成为优秀的多相催化剂。在水杨醛、苯酚或苯乙烯的氧化溴化过程中，固体载体的性质不影响底物转化率 (%)，而在硫醚氧化过程中，它会影响底物转化率 (%) 以及产物选择性 (%)。
