General Description

2-Methylbenzo[e]indene, also known as 2-MeBI, is a polycyclic aromatic hydrocarbon that is found in fossil fuels, particularly in gasoline and diesel exhaust. It is classified as a hazardous air pollutant and has been found to be a potential human carcinogen. Exposure to 2-MeBI has been linked to respiratory irritation and has also been shown to have mutagenic and genotoxic effects. The compound is formed during the incomplete combustion of organic matter and is commonly found in urban air pollution. Overall, 2-Methylbenzo[e]indene poses a significant risk to human health and the environment, making it an important target for regulatory and control measures.

Process for preparing 1-indanones

The present invention relates to a process for preparing 1-indanones of formula I: and isomers thereof, wherein R1, R2, R3, R4, R5, and R6 independently represent H or a C1-C20 hydrocarbon group or R1 and R2 or R2 and R3 or R3 and R4 and/or R5 and R6 together with the carbon atoms to which they are attached form a saturated or unsaturated 5- or 6-membered ring, said hydrocarbon group and/or said ring optionally containing one or more hetero atoms, said ring optionally being substituted with a C1-C4 hydrocarbon group, said process comprising reacting a compound of formula II: wherein R1, R2, R3, R4, R5, and R6 have the same meaning as defined above, with a chlorinating agent, followed by reaction with a Friedel-Crafts catalyst. The invention further relates to the preparation of the corresponding indenes.

Control of stereoerror formation with high-activity "dual-side" zirconocene catalysts: A novel strategy to design the properties of thermoplastic elastic polypropenes

The new C1-symmetric complexes rac-[1-(9-η5-fluorenyl)-2-(2-methylbenz[e]-1-η 5-indenyl)ethane]-zirconium dichloride (14a), rac-[1-(9-η5-fluorenyl)-2-(4,5-cyclohexa-2-methyl-1-η 5-indenyl)ethane]zirconium dichloride (14b), and rac-[1-(9-η5-fluorenyl)-2-(5,6-cyclopenta-2-methyl-l-η 5-indenyl)ethane]zirconium dichloride (15) were prepared in up to 93% yield. These compounds, activated with methyl aluminoxane, exhibit high active propene polymerization rates which remain constant over hours, even at elevated polymerization temperatures of 50 and 70°C. The two different coordination sites of these "dual-side" catalysts lead to isotactic polypropenes with variable amounts of stereoerrors, depending on the monomer concentration. The 2-methyl substituent of the indenyl ligands results, at the same time, in significantly increased molecular weights of the polymer products (up to 2.3 × 105 g mol-1), the bulk properties of which can be adjusted from flexible, semicrystalline thermoplastic to excellent thermoplastic elastic.

Process for preparing cyclopentadienyl group-containing silicon compound or cyclopentadienyl group-containing germanium compound

Disclosed is a process for preparing a cyclopentadienyl group-containing silicon compound or a cyclopentadienyl group-containing germanium compound, comprising reacting (i) a lithium, sodium or potassium salt of a cyclopentadiene derivative with (ii) a silicon halide compound or a germanium halide compound in the presence of a cyanide or a thiocyanate. The cyanide or the thiocyanate is preferably a copper salt. According to the process of the invention, a cyclopentadienyl group-containing silicon compound or a cyclopentadienyl group-containing germanium compound, which is very useful for the preparation of a metallocene complex catalyst component, can be prepared in a high yield for a short period of time.
