Preferred Label : stereospecificity;
Detailed label : stereospecificity (stereospecific);
IUPAC definition : the term has also been applied to describe a reaction of very high stereoselectivity,
but this usage is unnecessary and is discouraged.; a reaction is termed stereospecific if starting materials differing only in their
configuration are converted into stereoisomeric products. according to this definition,
a stereospecific process is necessarily stereoselective but not all stereoselective
processes are stereospecific. stereospecificity may be total (100%) or partial. the
term is also applied to situations where reaction can be performed with only one stereoisomer.
for example, the exclusive formation of trans-1,2-dibromocyclohexane upon bromination
of cyclohexene is a stereospecific process, although the analogous reaction with (e)-cyclohexene
has not been performed.;
