摘要: 1-Alkenyl isocyanates are prepared by reacting aldehydes with carbamates to give N-(1-alkenyl)-carbamates and splitting these compounds at elevated temperatures. The 1,2-unsaturated isocyanates obtained are valuable starting materials for the preparation of pest control agents, dyes, drugs, textile water repellents, detergents, plastics, bleaches and adhesives, since they possess an activated double bond or an activated .alpha.-carbon atom, in addition to a reactive isocyanate group.
