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

open access: closedJournal 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%

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

open access: closedSynthesis, 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 ...
