Abstract: (57)【要約】 第4属の新規有機金属錯体は、1つのホスフィンイミン配位子と2つ又はそれより多いシクロペンタジエニル配位子を有することによって特性づけられる。 これらの錯体のある種のものは、核磁気共鳴(NMR)技法によって調べた時に、通常でない挙動を示す。 本発明の錯体の構造の確定している結晶は単離され、X線結晶学によって解析されている。 また、これらの錯体は、それらの単純なメタロセン類似体よりも、驚くほど活性が高い重合触媒であることが見出されている。

Abstract: PROBLEM TO BE SOLVED: To provide a new heterogeneous reaction method capable of readily carrying out separation, recovery and reutilization of a catalyst in a heterogeneous reaction using a solid catalyst, readily advancing reaction without forcibly moving the reaction product and the catalyst and reducing environmental loading or production cost as clean reaction system and an interfacial catalyst suitably applicable for the method. SOLUTION: In this heterogeneous reaction method comprising reacting substances to be reacted in a heterogeneous system containing a solid-like interfacial catalyst and forming liquid/liquid interface, the interfacial catalyst is arranged in a position at which the catalyst comes into contact with the liquid/ liquid interface and the reaction is carried out by using the liquid/liquid interface as a reaction zone.

Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently producing a high-purity linear α-olefin in a simple operation with improved catalytic activity and suppressed byproduct polymer formation. SOLUTION: This method for producing a linear α-olefin comprises oligomerization of ethylene in the presence of a Ziegler-Natta type catalyst; wherein the above catalyst is characterized by being prepared by incorporating an organometallic compound as the cocatalyst with 0.05-1 molar time, based on the organometallic compound, of a heterocompound with the electron density of the heteroatom determined by molecular orbital calculation being 5.8-6.5.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a (thio)ester condensate by catalytic esterification between equimolar amounts of a carboxylic acid and an alcohol or by catalytic thioesterification between a carboxylic acid and an equimolar or small excess amount of a thiol, thus hopeful as an industrial method needing mass synthesis from the standpoint of green chemistry. SOLUTION: This method for producing a (thio)ester condensate comprises the following process: a direct condensation reaction is made between a carboxylic acid and an equimolar amount of an alcohol or a small excess amount of a thiol in a nonpolar solvent such as toluene in a deoxygenation atmosphere under reflux while heating in the presence of a (poly)condensation catalyst consisting of a tetravalent hafnium compound represented by hafnium (IV) chloride, especially hafnium (IV) chloride.(THF)2 or hafnium (IV) t-butoxide to synthesize the objective monomeric (thio)ester or poly(thio)ester; wherein it is preferable that in making the reflux under heating using the nonpolar solvent, the azeotropic water is eliminated from the reaction system.
