text: In a reaction that is typically avoided, hydrolysis of carbamoyl chlorides gives carbamic acids:
  :RNCOCl + HO → RNC(O)OH + HCl
  Owing to the influence of the amino group, these compounds are less hydrolytically sensitive than the usual acid chlorides.
  A related but more useful reaction is the analogous reaction with alcohols:
  :RNCOCl + ROH + CHN → RNC(O)OR + CHNHCl
