COMPREHENSIVE SYSTEM FOR CLASSIFICATION AND NOMENCLATURE OF ORGANIC-REACTIONS

Previous authors' ideas on reaction classification have been incorpora ted into a unified and comprehensive system to record the bonding chan ge in any reaction. The system offers a ''reaction logo'' as a single drawing of the bonding change at the reaction center. It also provides a smooth hierarchy of increasing detail from the two monocyclic basic forms (homovalent and ambivalent), through their subclasses of unchan ging shell cr-bonds on the reaction center, to the full detail elf the individual atom types in the reaction center. A simple linear notatio n incorporates all of this information in a form such as -3(L)[OCCCOH] , for the reaction center of the aldol reaction.
