WebKonrad Julius Bredt (1855-1937) was a German organic chemist who is well known for the first determination of the correct structure of camphor in 1893. Bredt also discovered that a double bond cannot be placed at the bridgehead of a bridged ring system. The statement is today known as Bredt’s rule. Read more about the Julius Bredt Lecture here . WebSep 15, 2010 · Bredt's rule is an empirical formulation that may be stated in qualitative terms: a double bond cannot be placed with one terminus at the bridgehead of a bridged ring system, such as in [ x.y.z] bicyclic system ( x ≥ y ≥ z, z /= 0), unless the rings are large enough to accommodate the double bond without excessive strain (e.g., S = x + y ...
