The Ritter reaction is the one-flask reaction of a nitrile and a carbenium ion (or its chemical equivalent) to produce a nitrilium ion, followed by subsequent chemical events. The two principal outcomes are formation of an acyclic amide, or cyclization to yield a wide range of heterocyclic ...
When the reaction bar is used as a transmission member, as described, it can be interposed within the pedal module into the path of force of the restoring spring. This is best done on the path between the restoring spring and the cam plate. It is aimed at as an improvement of the in...
