Usage

General Description

2-Bromoethyl isocyanate is a chemical compound with the formula C4H6BrNO. It is a clear, colorless liquid that is highly reactive and has a strong, pungent odor. 2-BROMOETHYL ISOCYANATE is used in the production of various polymers and resins, as well as in the synthesis of pharmaceuticals and agricultural chemicals. It is also used as a reagent in chemical reactions to introduce isocyanate functional groups into organic molecules. Due to its highly reactive nature and potential health hazards, 2-Bromoethyl isocyanate should be handled with caution and proper safety measures. Exposure to this chemical can cause irritation to the skin, eyes, and respiratory tract, as well as potential damage to the central nervous system.

Alkylation of Nitrocyanamide. A New Synthesis of Isocyanates

Thirteen alkyl halides (primary, secondary, and tertiary aliphatic including alicyclic, aralkyl, and heteroalkyl systems) and certain non-vicinal dihalides on treatment with silver nitrocyanamide are converted into the corresponding isocyanates (63-95percent).Intermediate alkylnitrocyanamides, spectroscopically detected, thermolysed (-20-80 deg C) to the expected isocyanates.In certain examples silver nitrocyanamide is generated in situ from sodium nitrocyanamide and silver nitrate.Silver nitrocyanamide does not react with cyclopropyl bromide, acetyl chloride, toluene-p-sulphonyl chloride, phenacyl bromide and 2-bromomethyldioxolane (27), and the ethylene acetal (28) of 1-bromo-4-iodopentacyclo-nonan-9-one.Silver nitrocyanamide reacts with 4,6-bis(bromomethyl)-3,7-dimethyl-1,5-diazabicyclo3.3.0)octane-2,8-dione (26), to give an intractable mixture.Vicinal dihalides give erratic results without detectable formation of vicinal di-isocyanates: unisolated 2-bromoethyl isocyanate (tentative assignment) has been detected in a product mixture from ethylene dibromide; an expected rearrangement during the reaction with 1,2-dibromocyclobutane, brought about the formation of 4-bromobut-3-enyl isocyanate isolated as ethyl 4-bromobut-3-enylcarbamate in low yield; and 1,2-dibromocyclohexane gives 2-bromocyclohexyl isocyanate isolated as ethyl N-(2-bromocyclohexyl)-carbamate in low yield.
