The invention relates to a method for producing special transition metal compounds, to novel transition metal compounds and to the use of the same for the polymerisation of olefins.
The present invention relates to multifunctional chemosensors that can measure the concentration, enantiomeric excess (ee), and absolute configuration of chiral compounds. The chemosensors described herein may contain a backbone moiety that is bonded to a fluorescent moiety and a moiety for bonding a chiral compound. Backbone moieties may include aromatic groups, for example, naphthyl. The chemosensors described herein are useful for measuring concentration, enantiomeric excess, and absolute configuration of organic molecules in areas such as high throughput screening.

The reaction of tropone and potassium hydroxide in the presence of potassium ferricyanide gave tropolone, salicylaldehyde, and p-hydroxybenzaldehyde, while in the presence of the copper ammine complex it afforded 2-aminotropone and salicylonitrile. Similarly, when tropone was reacted with aqueous ammonia, methylamine, or dimethylamine, 2-aminotropone and its N-methyl derivatives were formed. The reaction of 2-phenyltropone with ammonia and methylamine, and the reaction of 2-α-naphthyltropone and 4-bromo-2-phenyltropone with methylamine in the presence of copper salt, also afforded 2-aminotropone derivatives and/or salicylaldehyde derivatives.
