Reactions of Group IV organometallic compounds. Part XXVI. Insertion reactions of isocyanates and isothiocyanates to N-trimethylsilyl-(diphenylmethylene)amine and subsequent [4 + 2] cycloadditions of isocyanates with their adducts

open access: closedJournal of the Chemical Society, Perkin Transactions 1, 1972
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.

Formation of copper(I) isocyanate complexes by the reaction of carbon dioxide and copper(I) bis(trimethylsilyl)amide complexes

open access: closedJournal of the Chemical Society, Chemical Communications, 1977
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

open access: closedSynthetic Communications, 1972
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.

Reaction of trimethylsilyl cyanide with isocyanates and carbodiimides

open access: closedJournal of Organometallic Chemistry, 1979
Abstract Trimethylsilyl cyanide reacts with isocyanates to give 1 2 cycloadducts, 5-(trimethylsilylimino)imidazolidine-2,4-diones, in high yield. The reaction of trimethylsilyl cyanide with carbodiimides proceeded in the presence of a catalytic amount of aluminum trichloride to afford 1 1 adducts, N-trimethylsilyl-1-cyanoformamides.
