    Abstract: PROBLEM TO BE SOLVED: To produce the subject compound useful for the dehydrohalogenation of organic compounds or synthesis, etc., of polymers in high yield without requiring the use of an acidic catalyst by reacting a specific lactone with a specified diamine while removing water of reaction during the progress of the reaction. SOLUTION: A lactone represented by formula I [R and R are each H or the like; (m) is 2-12] (e.g. γ-butyrolactone) is reacted with a diamine represented by formula II [R and R are each H or the like; (n) is 2-12] (e.g. 1,3-diaminopropane), preferably in at least 1:1.5 initial molar ratio of the lactone to the diamine, preferably continuously over the total reactional time, preferably at 170-220 deg.C for 5-100 hr while eliminating water of reaction and preferably with the aid of an azeotropic agent to produce the objective compound represented by formula III e.g. 1,5-diazabicyclo[4.3.0]non-5-ene}.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound by reaction between an α,β-unsaturated nitrile and an alcohol using a specific diazabicycloalkene as basic catalyst without the need of any prior separation or neutralization of the catalyst for the addition reaction.
    SOLUTION: This compound is obtained by reaction between an α,β-unsaturated nitrile (e.g. acrylonitrile) and a monohydric, dihydric or trihydric alcohol (e.g. methanol, ethanol, 2-ethylhexanol, 2-methoxyethanol, benzyl alcohol) at -20 to 200°C using a diazabicycloalkene of the formula (H may be substituted with a 1-20C alkyl, 6-20C aryl or 7-20C arylalkyl; (n) and (m) are each 1-6) as basic catalyst {e.g. 1,5-diazabicyclo[4.3.0]nonene-5(DBN), 1,8- diazabicyclo[5.4.0]undecene-7(DBU)}; wherein the amount of the catalyst to be used is pref. 0.05-5 wt.% based on the alcohol.

    Abstract: Preparation of bicyclic amidine derivatives with continual removal of water during reaction. Bicyclic amidine derivatives of formula (1) are prepared by reacting a lactone of formula (2) with a diamine of formula (3), during which water is removed while the reaction is taking place. Rx, Ry, Ra, Rb = independently H, or 1-10C alkyl, 2-10C alkenyl, 2-10C alkynyl or 6-12C aryl, optionally substituted by OH, NH2, 1-4C alkylamino or SH; m, n = 2-12; a, b, x and y actually = number of carbon atoms in the R groups, which correspond to values of n+1 or m+1. Independent claims are also included for the following: (I) A diazacycloalkane of formula (4); (II) Preparation of diazacycloalkane (4); and (III) Use of diazacycloalkane (4) as an intermediate in production of bicyclic amines of formula (1). Rx, Ry, Ra, Rb = independently H, or 1-10C alkyl, 2-10C alkenyl, 2-10C alkynyl or 6-12C aryl, optionally substituted by OH, NH2, 1-4C alkylamino or SH; m, n = 2-12; a, b, x and y actually = number of carbon atoms in the R groups, which correspond to values of n+1 or m+1.
