    Abstract: Preparation of N-hydroxyalkyl -substituted amino-alkynol derivatives of formula (I) involves reaction of an alkyne of formula R1-C IDENTICAL CH (II) with a 1-oxa-3-aza-heterocycloalkane of formula (III) over a heterogeneous catalyst comprising a compound of a first or second transition group metal. R1= H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl, hydroxyalkyl or -CR2R3-N(R4)-A-OH; R2-R4 = H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl or hydroxyalkyl; A = 2-5C alkylene (optionally substituted by one or more of alkyl, haloalkyl, aryl, alkoxy, hydroxy and hydroxyalkyl).

    Abstract: Preparation of hydroxy-alkyl substd. amino-alkyne derivatives of formula R1-C IDENTICAL C-CR2R3-NR4R5 (I) is claimed in reaction by the heterogeneously catalysed reaction of an alkyne of formula R1-C IDENTICAL CH (II), a carbonyl compound of formula O=CR2R3 (III) and an amine of formula H-NR4R5 (IV). R1 = H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl or hydroxyalkyl; R2, R3 = H, alkyl, haloalkyl, aryl or alkoxy; R4, R5 = H, alkyl, haloalkyl, aryl, alkoxy or hydroxyalkyl; or NR4R5 = a 5-6 membered heterocyclic ring; providing that at least one of R1, R4 and R5 = hydroxyalkyl.

    Abstract: Prepn. of N-alkenyl azoles of formula (I) is by reaction of azoles (II) with alkenyl carboxylic acid esters (III) at 0-180 degC/0.01-10 bar. The novel feature being that the reaction is in presence of a base and a quat. salt. X = CHR or N; R and R = H or 1-8C alkyl R -R = H; 1-40C alkyl; 2-40C alkenyl; 3-20C cycloalkyl; 4-20C alkylcycloalkyl or cycloalkyl-alkyl; or aryl or 7-20C alkaryl or aralkyl each opt substd up to 5 times by 1-8C alkyl or alkoxy or halogen; or R +R , R +R or R +R together form a 2-10C alkylene chain opt. substd. up to 6 times by 1-8C alkyl; and R = H; 1-40C alkyl; 3-20C cycloalkyl; 4-20C alkyl-cycloalkyl; aryl or 7-20C aralkyl, each opt. substd. up to 3 times by 1-8C alkyl; or 7-20C alkaryl.

    Abstract: Distillative recovery of alpha -ethynyl-carbinols (I) from the liquid reaction mixture from the addition of acetylene to alpha , beta -unsaturated carbonyl compounds comprises continuous distillation, in which the feed is passed to the middle of the distillation column, most of the water is distilled off at the top as azeotrope with the solvent and (I) is recovered below the feed port.
