Document Summary
In resonance, they are more stable and less reactive. Arylamines are less basic than alkylamines because the nitrogen lonepair electrons are delocalized by interaction with the aromatic rings pi electron system. Biological amines and the henderson-hasselbalch equation ph = pka +log [a-]/[ha] log[a-]/[ha] = ph - pka. Preparing an amine by reaction of an aldehyde or ketone with ammonia and a reducing agent. Friedel craft alkylations and acylation of n-arylamides proceed normally. Nucleophilic substitution reaction of an arenediazonium salt with a curprous halide to yield an aryl halide. Diazonium coupling reactions usually reacts with the para position.
