Morpholinophosphorodichloridate and dichloridothioate reacted with amines (2 molar equivalents) to give the amidic chlorides which were treated with nucleophilic reagents to give sixty-four derivatives. However the dichloridothioate with primary amines (1 molar equivalent) only gave diamidic thioates, the reasons for the failure to obtain the expected amidochloridothioates are briefly discussed.
