Abstract: N-alkyl formamides or the corresponding N-cycloalkyl or Naralkyl formamaides are prepared by reacting olefins, cycloolefins or aralkenes with hydrogen cyanide in the Ritter reaction using about 2.5 moles of acid per mole of olefin at a temperature of 30* to 70* C. and the unneutralized acid reaction mixture is extracted with acid stable polar solvents and the extract is worked up in conventional manner.
