Izocianai
Izocianai are a class of organic compounds characterized by the functional group R-N=C=O, where R is an organic substituent. This functional group, the isocyanate group, is highly reactive, particularly with nucleophiles. The presence of the cumulated double bonds in the N=C=O structure contributes to this reactivity. Isocyanates are typically synthesized through the reaction of amines with phosgene or phosgene equivalents. This reaction is a crucial step in the industrial production of many polymers.
The most prominent application of isocyanates is in the production of polyurethanes. Diisocyanates, such as toluene
Beyond polyurethanes, isocyanates are used as intermediates in the synthesis of pesticides, herbicides, and pharmaceuticals. However,
