Nitrogen Quadrupole Coupling in the Microwave Ground State Spectra of Tertiary Butyl Isocyanide and Phenyl Isocyanide
نویسنده
چکیده
Z. Naturforsch. 41 a, 1302-1306 (1986); received August 7, 1986 The microwave ground state spectra of tert.-butyl isocyanide, (CH3)3CNC, and phenyl isocyanide, C6H 5NC, have been measured by microwave Fourier transform spectroscopy in the region 5.0 to 8.0 GHz and analysed for nuclear quadrupole hyperfine splitting due to ‘*N. The nuclear quadrupole coupling constants are shown to be in accordance with structural predictions of the p-electron population at the nitrogen atom. The dipole moment of phenyl isocyanide was derived from the Stark effect of the JK K+ = 202 10i transition.

Towards molecular diversity: dealkylation of tert-butyl amine in Ugi-type multicomponent reaction product establishes tert-butyl isocyanide as a useful convertible isonitrile.
With the development of a novel microwave-assisted one-pot tandem de-tert-butylation of tert-butyl amine in an Ugi-type multicomponent reaction product, tert-butyl isocyanide as a useful convertible isonitrile has been explored for the first time affording access to molecular diversity of pharmaceutically-important polycyclic N-fused imidazo-heterocycles.

متن کاملBinding of aromatic isocyanides on gold nanoparticle surfaces investigated by surface-enhanced Raman scattering.
The adsorption structure and binding of phenyl isocyanide (PNC), 2,6-dimethyl phenyl isocyanide (DMPNC), and benzyl isocyanide (BZI) on gold nanoparticle surfaces have been studied by means of surface-enhanced Raman scattering (SERS). PNC, DMPNC, and BZI have been found to adsorb on gold assuming a standing geometry with respect to the surfaces. The presence of the nu(CH) band in the SERS spect...
