The reaction of potassium cyanamide with normal alkyl bromides
摘要:
A study was carried out on the reaction of potassium cyanamide with normal alkyl bromides in 2-propanol, methanol, and dimethylformamide in order to obtain dialkylcyanamides. A virtually quantitative yield of dialkylcyanamides is achieved in dimethylformamide.

'~'~ all have drawbacks. Alkylation of hexadecyl or octadecylamine with the corresponding bromoaIkane,l5 reduction with of N-hexadecylhexadecanamide with LiA1H41h and NaBH, reduction of the imines obtained from hexadecyl or octadecylamine and the corresponding aldehydes' give only moderate yields (3040%). The four steps of a new approach for the preparation of secondaryamines (including 4b)" make it
