Abstract: Method for the preparation of 4-hydroxymethyltetrahydropyrans of the general formula I in which R , R , R and R denote hydrogen, C1- to C12-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C20-aralkyl, by reacting tetrahydropyrancarboxylic esters of the general formula II in which R1, R2, R3 and R4 have the abovementioned meanings and R5 denotes hydrogen or C1- to C12-alkyl, at temperatures of 50 to 400 DEG C and pressures of 1 to 400 bar in the presence of hydrogen and hydrogenation catalysts.

Abstract: N-alkenylcarboxylic acid amides of formula HR C=CRN(R )C(O)R (I) are prepd. from carboxylic acid alkenyl esters of formula HR C=CR OC(O)R (II) and a carboxamide of formula HNR NC(O)R (III), by reaction in presence of a base. In formulae, R = one is H and the other is H or 1-4 C alkyl; R = (cyclo)aliphatic, araliphatic or aromatic gp., which may form a 3-10-member bridge with R ; R = H, or a (cyclo)aliphatic or aromatic gp.; and R = H or a (cyclo)aliphatic or aromatic gp. Pref. N-vinylpyrrolidone or N-vinylcaprolactam are prepd. Reaction is at 20-80 degrees C, without a solvent, using a tert. amine or Na methylate, K tert.butylate or K2CO3 as base. The amt. of base is 0.2-1 equivs. w.r.t. 1 equiv. of amide (III).

Abstract: The invention concerns a method of hydrogenating aromatic compounds in which at least one amino group is bonded to an aromatic nucleus, the catalyst containing ruthenium and optionally at least one metal of the I, VII- or VIII subsidiary group in an amount of between 0.01 and 30 wt.% relative to the total weight of the catalyst, applied to a carrier. The carrier has an average pore diameter of at least 0.1 mu m and a surface area of at most 15 m /g.

Abstract: 2-Methyl-1,4-butanediol and 3-methyltetrahydrofuran are prepared by reacting compounds of the general formulae I and II in which R and R represent hydrogen or a C1-C8-alkyl group and the formyl group of II can also exist as an acetal with C1-C8-alkanols, in the presence of copper or a metal of groups 7 to 10 of the Periodic Table or of compounds of these metals with hydrogen.
