WebPhenylisothiocyanate and phenylisocyanate adds to 2-amino-2-thiazoline (79) to give the corresponding adducts 〈86JOC1910〉. The reaction of ( 79) with phenyl isothiocyanate … Isocyanates are electrophiles, and as such they are reactive toward a variety of nucleophiles including alcohols, amines, and even water having a higher reactivity compared to structurally analogous isothiocyanates. Upon treatment with an alcohol, an isocyanate forms a urethane linkage: where R and R' are alkyl or aryl groups. If a diisocyanate is treated with a compo…

WebThe method is based on the preparation of a urea derivative, by treatment of a primary amine or sulfonamide with a readily available alkyl or aryl isocyanate ( Equation (22) ), which in a second step is phosgenated ( Equation (23)) to … Webthen continued our research on the synthesis of phenyl isothio-cyanate by the desulfurylation of 2-1 with TCT. We found out that the reaction between N-phenyl dithiocarbamate and TCT proceeded rather fast, even at a lower temperature (0 °C), and 0.5 equiv of TCT was proved to be necessary for a complete conversion of N-phenyl … WebPoly-2-oxazolidones of high molecular weight have been synthesized from diisocy anates and diepoxides. The synthetic method was first developed for the model compound 3-phenyl-5-phenoxymethyl-2-oxazolidone prepared from phenyl isocyanate and phenyl glycidyl ether. Conditions found most suitable for a high yield involve slow addition of isocyanate … grief share tucson az
