In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
A full edition was published in 1979, [1] an abridged and updated version of which was published in 1993 as A Guide to IUPAC Nomenclature of Organic Compounds. [2] Both of these are now out-of-print in their paper versions, but are available free of charge in electronic versions.
Quantities, Units and Symbols in Physical Chemistry, commonly known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants, tables listing the properties of elementary particles, chemical elements, and nuclides, and information about conversion ...
For example, the three isomers of xylene CH 3 C 6 H 4 CH 3, commonly the ortho-, meta-, and para-forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. The cyclic structures can also be treated as functional groups themselves, in which case they take the prefix "cyclo alkyl -" (e.g. "cyclohexyl-") or for benzene, "phenyl-".

In organic chemistry, the Murai reaction is an organic reaction that uses C-H activation to create a new C-C bond between a terminal or strained internal alkene and an aromatic compound using a ruthenium catalyst. [1] The reaction, named after Shinji Murai, was first reported in 1993.
The Oxford Chemistry Primers are a series of short texts providing accounts of a range of essential topics in chemistry and chemical engineering written for undergraduate study. The first primer Organic Synthesis: The Roles of Boron and Silicon was published by Oxford University Press in 1991. [ 1 ]
