Preferred Label : Walden inversion;
IUPAC definition : Retention of configuration is the preservation of integrity of the spatial arrangement
of bonds to a chiral centre during a chemical reaction or transformation. It is also
the configurational correlation when a chemical species Xabcd is converted into the
chemical species Xabce having the same relative configuration. The configurational
change when a chemical species Xabcd (where X is typically carbon), having a tetrahedral
arrangement of bonds to X, is converted into the chemical species Xabce having the
opposite relative configuration (or when it undergoes an identity reaction in which
Xabcd of opposite configuration is produced) is called a Walden inversion or inversion
of configuration. The occurrence of a Walden inversion during a chemical transformation
is sometimes indicated in the chemical equation by the symbol shown below in place
of a simple arrow pointing from reactants to products.;
