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]
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 ...

N-Trimethylsilyl(diphenylmethylene)amine reacted with 1 mol. equiv. of methyl, phenyl, or benzoyl isocyanate, and with the corresponding isothiocyanates, by the selective cleavage of the Si–N bond. The n.m.r. spectra of the 1:1 insertion product (III)–(VIII) showed the non-equivalency of trimethylsilyl proton signals at low temperature.

Copper(I) bis(trimethylsilyl)amide deoxygenates carbon dioxide in the presence of an added ligand to produce hexamethyldisiloxane and a copper(I) isocyanate complex which is converted into an alkyl isocyanate by treatment with an alkyl iodide.

Curtius Degradation Utilizing Trimethylsilyl Azide. A facile isocyanate synthesis
Abstract We wish to report a modification of the Curtius Degradation which facilely affords high yields of isocyanates from acid chlorides or anhydrides under “single-pot” conditions. Trimethylsilyl acide attacks the reactive carbonyl groups of cyclic anhydrides and isomaleimides according to Eqn. 1, giving formally a Curtius Degradation product.
