![]() The systematic name ethenyl is the preferred IUPAC name.Īlso in preferred IUPAC names, stereodescriptors are preceded by a numerical or letter locant to describe the position of the stereogenic unit when such locants are present. In particular, the name vinyl for $\ce$ is retained for general nomenclature only. The current version of Nomenclature of Organic Chemistry – IUPAC Recommendations and Preferred Names 2013 (Blue Book) includes the definition of a preferred IUPAC name (PIN), which is the name preferred among two or more names generated from two or more IUPAC recommendations including also the many retained names. Also note that the IUPAC recommendations have changed several times and the current (2013) recommendations are not included in ChemOffice yet. Note that a compound may be named correctly in two or more ways in accordance with the several methods recommended by IUPAC. Click on “Activate” and then your new ChemDraw should work until April 5, 2026.The names given by ChemOffice are not wrong since they describe the correct structures and are in accordance with IUPAC nomenclature rules.
