2,4,6-Trimethylphenyl isocyanide
Acta Crystallographica Section C Crystal Structure Communications, 2002The title compound, C(10)H(11)N, displays a crystallographic mirror plane that incorporates all the non-H atoms, as well as the H atoms attached to the aromatic ring. The isocyano group is almost linear and shows an N[triple bond]C bond distance of 1.158 (3) A.

Fluoromethyl isocyanide and difluoromethyl isocyanide
Journal of Fluorine Chemistry, 1991Abstract Whereas methyl isocyanide is known since more than a hundred years, the chemistry of its perfluorinated derivative CNCF 3 , has been developed only recently. Both compounds differ drastically. Herein we report the syntheses of the missing partially fluorinated compounds CNCH 2 F and CNCHF 2 via their pentacarbonyl chromium complexes.

Isocyanide-Based Multicomponent Reaction ‘without’ Isocyanides
Synlett, 2009We present here a one-pot, four-component sequence that affords Ugi-type adducts starting from simple benzyl or allyl bromides. The isocyanides are prepared in situ under alkylation of silver cyanide salts and the resulting mixture is directly used in a Ugi―Smiles coupling.

Homoleptic Isocyanide Metalates
Angewandte Chemie International Edition, 1998Novelties and surprises in the chemistry of metal isocyanides: The synthesis and structure determination of homoleptic isocyanide metalates [M(CNXyl)m ]- (M=Co, m=4; M=Mn, m=5; Xyl=2,6-Me2 C6 H3 ) indicate that we need to revise our understanding of transition metal-isocyanide interactions.

Functional Isocyanide-Based Polymers
Accounts of Chemical Research, 2020Research interest in the isocyanide-based reaction can be traced back to 1921 when the Passerini reaction was first reported. However, most of these research efforts did not lead to important progress in the synthesis of isocyanide-based polymers (IBPs).

Acta Crystallographica Section C Crystal Structure Communications, 2004
Achiral p-nitrophenyl isocyanide, C(7)H(4)N(2)O(2), crystallizes in the orthorhombic chiral space group P2(1)2(1)2(1). Attractive intermolecular interactions between the nitro O atoms and both aromatic H and nitro N atoms of neighbouring molecules are observed.

Microchemical detection of isocyanides
Talanta, 1967Microgram quantities of isocyanides may be easily detected on filter paper or in tubes of silica gel by using benzidine acetate-copper(II) acetate or p,p'-tetramethyldiaminodiphenylmethane-copper(II) sulphate reagents. Interferences include those substances which are known to interfere in the use of the same reagents for the detection of hydrogen ...
