The International Union of Pure and Applied Chemistry (IUPAC) name of a ketone is derived by selecting as the parent the longest chain of carbon atoms that contains the carbonyl group. Metallocene None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction mechanisms and may exist as reactive intermediates. The suffixes used in the nomenclature of compounds which have a functional group containing a C-O bond are tabulated below along with examples. This is the procedure used in reactions 2 and 3. In organic chemistry, ethers are a class of compounds that contain an ether groupan oxygen atom connected to two alkyl or aryl groups. The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents. [1] Functional Group Priorities for Nomenclature In contrast to the more strict definition proposed by International Union of Pure and Applied Chemistry, which requires a d-block metal and a sandwich structure, the term metallocene and thus the denotation -ocene, is applied in the chemical literature also to non-transition metal compounds, such as barocene (Cp2Ba), or structures where the aromatic rings are not parallel, such as found in manganocene or titanocene dichloride (Cp2TiCl2). It reacts with metal halides to give thallium chloride, which is poorly soluble, and the cyclopentadienyl complex. 7.5.8 Relative Ease of Hydrolysis.
