A variety of β-enaminoketones and esters have been synthesized in high to exellent yields by reacting β-dicarbonyl compounds with amines in the presence of a catalytic amount of indiumtribromide. The reaction proceeds smoothly at room temperature in a short reaction time under solvent-free conditions.

Organic compounds containing heteroatoms and their use in preparing Ziegler-Natta (Z-N) catalyst with single activation center. The Z-N olefin polymerization catalyst is prepared by adding organic or inorganic solid carrier or compound of them which is pre-activated by heating or pre-treated chemically, organic compound containing heteroatoms and metallic compound into magnesium compound/tetrahydrofuran solution. The Z-N olefin polymerization catalyst prepared in the present invention is fluidizable powder and can prepare ethene homopolymer and copolymer of controllable construction with high catalytic activity, during homo-polymerization and combined polymerization with alpha-olefin of C3-C8 under action of catalyst promoter such as alkyl aluminium, alkyl aluminoxane, and so on.
