N2-phosphinyl formamidine compounds and N2-phosphinyl formamidine metal salt complexes are described. Methods for making N2-phosphinyl formamidine compounds and N2-phosphinyl formamidine metal salt complexes are also disclosed. Catalyst systems utilizing the N2-phosphinyl formamidine metal salt complexes are also disclosed along with the use of the N2-phosphinyl amidine compounds and N2- phosphinyl amidinate metal salt complexes for the oligomerization and/or polymerization of olefins.
phosphorus sites, complexes [Fe(κ3-P,N,P-PNPPh-Et)Cl2] and [Fe(κ3-P,N,P-PNPPh-nPr)Cl2] were formed, revealing that sterics can be also controlled by substituent variations at the amino N-sites. Depending on the solvent, complexesfeaturing κ2-P,N-bound ligands undergo facile rearrangement reactions to give dicationic complexes of the type [Fe(κ3-P,N,P-PNP)2]2+ where both PNPligands are bound in a κ3-P,N
Dialkyl- and diaryl(cyanomethyl)phosphines were conveniently prepared-in 61- 93% yields by the reacion of the corresponding diorganochlorophosphine with the lithium derivative of acetonitrile.
A method for producing a high purity, high quality amide compound, particularly a lactam. An amount of each of a halide, an aldehyde compound, an alcohol compound and a nitrile compound contained in a solution recycled into an oxime-forming step is controlled to an amount of 0.4 mol % or less based on the ketone as a starting material. One or more of a ketone, an oxime and an amide compound are purified by hydrogenation and/or crystallization for eliminating impurities containing a double bond. A content of impurities having a cyclic bridge structure is controlled using a cycloalkanone purified by recrystallization.
