The production of N-(1-alkenyl)-carbamyl chlorides by reaction of a Schiff base with phosgene, and the new N-(1-alkenyl)-carbamyl chlorides themselves. The new compounds which can be prepared by the process of the invention are valuable starting materials for the production of coating intermediates, plastics, paints and plant protection agents. One preferred group of compounds available from said process are the N-vinyl compounds of the formula ##STR1## in which R.sup.1 is cyclohexyl, cyclooctyl, norbornyl, tetrahydrodicyclopentadienyl, n-hexyl, n-octyl, 2-ethylhexyl or phenyl. Another preferred group of compounds are the N-vinyl-N-t-alkylcarbamyl chlorides of 4 to 6 carbon atoms in the tertiary alkyl group, especially N-vinyl-N-t-butylcarbamyl chloride.
该发明的方法可通过Schiff碱与光气反应生产N-(1-烯基)-氨基甲酰氯化物,以及这些新的N-(1-烯基)-氨基甲酰氯化物本身。该方法可制备的新化合物是生产涂料中间体、塑料、油漆和植物保护剂的有价值的起始原料。从该方法中可获得的一类首选化合物是公式为##STR1##中的N-乙烯基化合物,其中R.sup.1是环己基、环辛基、去氢脱环戊二烯基、正己基、正辛基、2-乙基己基或苯基。另一类首选化合物是具有4至6个碳原子的三级烷基基团的N-乙烯基-N-t-烷基氨基甲酰氯化物,特别是N-乙烯基-N-t-丁基氨基甲酰氯化物。
