    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in a high yield by the reaction of an alkyne with a carbonyl compound and an amine in the presence of a heterogeneous catalyst. SOLUTION: This compound, a hydroxyalkyl-substituted aminoalkyne of formula IV [e.g. 3-(di-2-hydroxyethylamino)propyne], is obtained by reaction of an alkyne of formula I (R1 is H, an alkyl, hydroxyalkyl, etc.) with a carbonyl compound of formula II (R2 and R3 are each H, an alkyl, aryl, alkoxy, etc..) and an amine of formula III (R4 and R5 are each H, an alkyl, hydroxyalkyl, etc., or joined together with a bound N atom to form a five- or six-membered ring) in the presence of a heterogeneous catalyst such as an acetylated copper catalyst carried on a bismuth-doped silicate support. By virtue of this method, the objective desired aminoalkyne can be obtained in high yield without the need of any special means for pH adjustment.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for reacting an organic compound by which the reaction of the organic compound is performed in extremely high yield or nearly complete conversion by using a specific catalyst. SOLUTION: All organic compound of a monomer and a polymer, especially an organic compound having a treatable group by hydrogen such as C-C double bond and C-C triple bond are reacted in the presence of a uniform ruthenium compound or a mixture of two or more kinds thereof deposited on a carrier in situ in the method for reacting an organic compound. The reaction is preferably hydrogenation, dehydrogenation, hydrogenolysis, amination hydrogenation or dehalogenation. The catalyst is the supported catalyst obtained by subjecting a solution of the ruthenium compound or two or more kinds thereof to pass through in the carrier or on the carrier to form the uniform ruthenium compound or mixture of two or more compound thereof deposited on the carrier. The smallest amount of a byproduct or a degrading product is formed during the hydrogenation and the reaction is performed without separation, after- treatment and recycle of the catalyst in the method.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound under low pressure by using a catalyst containing metal compounds of a first and a second subgroup elements and gaseous C2 H2 , etc., when carrying out the reaction of an alkyd with a 1-oxa-3- azaheterocycloalkane. SOLUTION: An N-hydroxyalkyl substituted aminoalkyne expressed by formula II is manufactured by reacting a mixture of a compound expressed by the formula R -C≡C-H(R is H, an alkyl, etc.) and a compound expressed by formula I (R , R are each H, an alkyl, etc.; A is a 2-5 alkylene) in the presence of a catalyst containing a metal compound of a first subgroup elements under a heterogeneous catalytic system. A suitable catalyst contains a complex of copper acetylide and Bi compound, for example, (BiO)2 CO3 , etc., the preferable catalyst contains about 40-70wt.% of Cu and about 0.1-10% of Bi. The reaction is carried out in a reactor such as a tubular reactor, etc., provided with a stirrer, generally at 0-200 deg.C, preferably at 20-120 deg.C, especially preferably at 40-120 deg.C.
