    Abstract: The prodn. of N-alkenyl ureas of formula (I) comprises reacting ureas of formula (II) with alkenyl carboxylate esters of formula (III), in which R , R = H, 1-40C alkyl, 2-40C alkenyl, 3-20C cycloalkyl, 4-20C alkyl-cycloalkyl or cycloalkyl- alkyl, or aryl, 7-20C alkaryl or 7-20C aralkyl (the last 3 opt. substd. with 1 to 5 halogen, 1-8C alkyl or 1-8C alkoxy gps.); or R + R = 2-10C alkylene (opt. substd. with 1 to 6 1-8C alkyl gps.); R , R = H or 1-8C alkyl; R = H, 1-40C alkyl, 3-20C cycloalkyl, 4-20C alkyl-cycloalkyl, aryl, 7-20C alkaryl or aralkyl, or substd. aryl or 7-20C aralkyl (with 1 to 3 1-8C alkyl gps.) The reaction is carried out at 0-180 degrees C and 0.01-10 bar in presence of a base.

    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.
