	Toluenesulphonylmethyl isocyanide (TOSMIC) and the van Leusen MCR
		Toluenesulphonylmethyl isocyanide (TOSMIC) and the van Leusen MCR
		It constitutes by far the most versatile synthon derived from methyl isocyanide and exhibits a multifaceted chemistry that is of great utility in organic synthesis.
		Figure 1 TOSMIC is a densely functionalized isocyanide, involving an isocyano group, an acidic α-carbon atom and a sulphonyl group.

	Isocyanide - Wikipedia, the free encyclopedia
		An isocyanide, also called an isonitrile, is an organic compound with the functional group R-N≡C. The CN functionality is connected to the organic fragment via the nitrogen atom, not via carbon as is found in the isomeric nitriles, which have the connectivity R-C≡N. Hence the prefix iso.
		Commonly, isocyanides are synthesized by the reaction of primary amines with dichlorocarbene or by dehydration of a formamide with phosphorus oxychloride.
		Isocyanides are reactants in two multicomponent reactions: the Ugi reaction and the Passerini reaction.

	Synthesis of substituted lactams - Patent 6054579
		The method comprises reacting a difunctional component containing an activated carbon, an amine capable of forming an imine with the activated carbon of the difunctional component, and an isocyanide in a nucleophilic polar protic solvent and at a concentration of reactants which facilitates the formation of the substituted lactams.
		The method comprises reacting a corresponding difunctional component (i.e., a.omega.-carboxyladehyde or a keto-acid), an amine and isocyanide in a nucleophilic polar protic solvent at a concentration suitable to form the lactam.
		Isocyanides suitable for use in the method include those selected according to the substitutent, R, which is desired in the final product(s).

	Poly(iminomethylene) copolymer from isocyanides - Patent 4704449
		Finally, the allylic isocyanide is isomerized to the corresponding vinyl isocyanide in the presence of a cuprous catalyst, such as cuprous oxide.
		Once the vinyl isocyanide monomer compounds are obtained, the monomers may be either homopolymerized to form a poly(vinyliminomethylene) homopolymer, or they may also be copolymerized with another isocyanide monomer to form a poly(vinyliminomethylene) copolymer.
		Thus, in instances where a particular isocyanide monomer does not, upon homopolymerization, result in the production of a soluble poly(iminomethylene), a soluble poly(iminomethylene) copolymer may be obtained by copolymerizing the isocyanide monomer yielding an insoluble homopolymer with an isocyanide having the isocyanide functionality attached to a sterically hindered carbon.

		This indicates that the excess electron density on the tungsten is being delocalized onto the isocyanide nitrogen with pairing effects causing the bend in the molecule.
		The formation of another bridging isocyanide bimetallic complex in which the second metal is in a high oxidation state (W(VI)) also provides strong evidence that charge can be polarized away from electron rich transition metal centers.
		The mixed isocyanide complex will be made by exploiting the fact that the first nitrogen replacement is much more facile than the second.

	Student Research Colloquium
		Previous work has shown, for short-chained isothiocyanates, a desulfurization (homolysis of the C-S bond) to form an isocyanide and triplet sulfur atom was the main mode of deactivation of the excited state.
		Other studies have shown that for longer chains, such as benzyl isothiocyanate, that isomerization of the isothiocyanate to the thiocyanate form was the dominant reaction.
		This is significant because isocyanide reagents are either expensive or not commercially available.

		Electron-rich transition metal complexes of organic isocyanides are of long established fundamental and practical interest because of their valuable role in organic and organometallic synthesis, catalysis, and radiological medicine.
		The positively-charged, functionalized complexes of isocyanoazulenes will be of particular synthetic interest in view of the recent advances in radiopharmaceutical and drug resistance research involving isocyanide complexes of 99mtechnetium and their non-radioactive analogs.
		The program will not only open a new chapter in the multi-faceted synthetic chemistry of metal isocyanides, but also have a significant potential impact across a broad spectrum of scientific disciplines encompassing polymer science, liquid crystal design, non-linear optics, organic synthesis, medicinal chemistry, and magnetic materials.

		The Passerini reaction is a 3-component condensation involving the reaction of an acid with a carbonyl compound and an isocyanide (Fig 1).
		Similarly the Ugi reaction is a 4-component condensation involving the reaction of a carbonyl compound with an amine in the presence of both an acid and an isocyanide (Fig 2).
		For the Passerini reactions the first position on the bar code was defined as the acid component, the second as the aldehyde and the third as the isocyanide.

	Halide - Wikipedia, the free encyclopedia
		Any organic compound that contains a halogen atom can be considered a halide.
		Alkyl halides are organic compounds of the type R-X, containing an alkyl group R covalently bonded to a halogen X. Pseudohalides resemble halides in their charge and reactivity; common examples are azides NNN-, isocyanate -NCO, Isocyanide, CN-, etc.
		A chemical test for the detection of halogen in chemical substances is the Carius halogen method.
