NEW MATERIAL:A compound shown by the formula I (R is H, 1-10C, aliphatic residue; R<1> and R<2> are H, or 1-10C hydrocarbon residue; R, R<1>, and R<2> which are plural, respectively, may not be the same). EXAMPLE:2,5-Diamino-1,4-dioxane. USE:Useful as an intermediate for drugs, agricultural chemicals, alpha-amino acids, etc., an addition agent for various purposes of thermosetting resins, thermoplastic resin, rubber including natural rubber, or synthetic rubber), or an intermediate for it. PREPARATION:A glycol aldehyde shown by the formula II is reacted with an ammonia or aliphatic primary amine shown by the formula RNH2 in a flowing inert gas such as nitrogen, argon, etc. in a closed system, to give a compound shown by the formula I . The reaction temperature is usually -10-100 deg.C and the reaction time is usually 1min-5 days.
