Reference of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

We present a C-H activation protocol for aromatic compounds that overcomes the current limitations of the need for a directing group or covalently bound activating groups, by exploiting the increase in C-H acidity of aromatic compounds on pi-coordination to a Ru(II) center. The increased acidity facilitates catalytic concerted metalation-deprotonation and subsequent arylation reactions. We present the development and optimization of the C-H activation protocol and show the applicability of the reaction to a range of aromatic substrates, including the simplest of substrates (benzene). Furthermore, we demonstrate the recyclability of the activating Ru(II) fragment using photolysis and give a mechanistic study, which provides strong evidence that this reaction occurs via a silver-mediated C-H bond activation. This is the first time Ru complexes have been shown to allow C-H activation of arenes by a pi-coordination mechanism.
