摘要:A one pot process is provided in which a Mannich base of the formula 5 is reacted with acetic anhydride to produce a diacetate derivative. Without any intermediate isolation, the derivative is hydrogenated to produce a reaction mixture containing 1-acetoxy-2-methylnaphthalene which is readily precipitated from the reaction mixture by addition of water. ##STR1##

摘要:Novel α-diimine metal complexes, particularly iron complexes, having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are disclosed. The α-diimine metal complexes having a phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are produced by forming one of the α-diimine metal complex imine bonds in the presence of a metal salt or an α-acylimine metal complex. The α-diimine metal complexes having phenyl sulfidyl or substituted phenyl sulfidyl metal complexing group are useful for polymerizing or oligomerizing olefins.

摘要:Methods for making α-diimine metal complexes are described. The methods comprise forming an α-diimine metal complex imine bond in the presence of a metal salt or an α-acylimine metal complex. The method is particularly using for the production of α-diimine metal complexes having two different α-diimine nitrogen groups. The α-diimine metal complexes are useful for polymerizing or oligomerizing olefins.

摘要:Methods for making α-diimine metal complexes are disclosed. The methods comprise forming an α-diimine metal complex imine bond in the presence of a metal salt or an ce-acylimine metal complex. The method is particularly using for the production of α-diimine metal complexes having two different α-diimine nitrogen groups. The α-diimine metal complexes are useful for polymerizing or oligomerizing olefins. Novel α-diimine metal complexes, particularly iron complexes are disclosed. The α-diimine metal complexes are produced by forming one of the α-diimine metal complex imine bonds in the presence of a metal salt or an α-acylimine metal complex, α-diimine metal complexes having two different α-diimine nitrogen groups may be produced. The α-diimine metal complexes are useful for polymerizing or oligomerizing olefins. Processes to polymerize or oligomerize olefins by contacting olefins with α-diimine metal complexes are disclosed. In particular, alpha olefins can be produced in high selectivity by contacting ethylene with selected α-diimine metal complexes.
