"Remarkable among Wurtz's earliest discoveries was his

fulfillment of Liebig's prediction that there might be organic

compounds analogous to ammonia and derivable from it by the

replacement of hydrogen. Having prepared substituted ureas

from derivatives of cyanogens, Wurtz investigated the action of

potassium hydroxide on his products and thus obtained the

primary amines (1849). This outstanding discovery was soon

extended by his friend Hoffman, who demonstrated that the

remaining two equivalents of hydrogen in ammonia could be

replaced by alkyl groups." [DSB].
