The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl ether compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

Methods for oligomerizing olefins with chromium pyridine ether catalysts

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a chromium based catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl thioether compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

Methods for oligomerizing olefins with chromium pyridine thioether catalysts

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl amine or a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

The instant invention provides methods for identifying agents that modulate an enzymatic activity of a carbohydrate sulfotransferase. The methods generally involve contacting the sulfotransferase, in a reaction solution, with a sulfate donor, a test agent, and a polymeric sulfate acceptor that is readily separated from the reaction solution. Determination of an effect of the test agent on the sulfotransferase is by detecting the amount of sulfate in the polymeric sulfate acceptor that has been separated from the reaction solution. The invention further provides kits for use in carrying out the subject methods.
