ChemInform Abstract: N‐ALKYLIDENE CARBAMOYL ISOCYANATES. REACTION OF TERTIARY α‐FLUOROAMINE WITH TRIMETHYLSILYL ISOCYANATE

Chemischer Informationsdienst, 1980
AbstractDas Fluoramin (I) reagiert mit dem Isocyanat (II) bei 0 °C unter Bildung eines l:2‐Addukts (III); dieses Addukt zerfällt im Vakuum wieder in die Ausgangsverbindungen, bei 20°C geht es in das N‐F1uorcarbonyl‐amidin (IV) über.

A New and Convenient Method of Generating Alkyl Isocyanates from Alcohols­, Thiols and Trimethylsilyl Ethers Using Triphenylphosphine/2,3-Dichloro-5,6-dicyanobenzoquinone/Bu₄NOCN

Synthesis, 2005
Alkyl isocyanates are prepared in good to excellent yields by treatment of alcohols, thiols and trimethylsilyl ethers with triphenylphosphine/2,3-dichloro-5,6-dicyanobenzoquinone/ Bu 4 NOCN in acetonitrile. This method is highly selective for conversion of primary alcohols to alkyl isocyanates in the presence of secondary and tertiary alcohols, thiols ...

Isocyanates derived from fatty acids by the trimethylsilyl azide modification of the curtius rearrangement

Journal of the American Oil Chemists' Society, 1972
AbstractFive fatty acid chlorides—myristoyl (14:0), palmitoyl (16:0), linoleoyl (18:2), oleyl (18:1) and stearoyl (18:0)—were smoothly converted in a one‐pot, one‐step reaction to the isocynates with one less carbon atom in the alkyl chain by treatment with trimethylsilyl azide in aromatic solvents at 100 C. The yields were consistently greater than 70%
