XCN (X = Cl, Br and I): a novel source of isocyanogen
摘要:
Ambient light photolysis of gaseous BrCN, ClCN, and ICN results in the production of isocyanogen (NCNC) as the sole CN containing product. The flash vacuum pyrolysis of BrCN (1100 degrees C and 10(-5) mbar) generates NCNC, NCCN, HOCN, HNCO and the CN radical.

The molecule CNCN, isocyanogen, has been identified on the basis of its vibrational and rotational spectra. Three of the five vibrational fundamentals have been recorded in the infrared with high resolution. The microwavespectra of the parent species and both 13C-substituted species in natural abundance have been measured, and a preliminary structure determined.
The flashvacuumthermolysis of norbornadienone azine over the temperature range 300 to 800°C was investigated by matrixisolation IR methods. The following thermolysis products could be identified: isocyanogen, cyanogen, benzene, benzonitrile and hydrogen cyanide. A tentative assignment of the infrared-active ν2 stretching vibration of diisocyanogen, CNNC, in an argon matrix is made. The peak positions

of three novel pseudohalides, namely, chloronitrile sulfide (ClCNS), chlorine isothiocyanate (ClNCS) and cyanogen N‐sulfide (NCCNS), was provided by direct spectroscopic methods supported by quantum chemical calculations. Ground‐state geometries, vibrational frequencies, IR intensities, and UV excitation energies of ClCNS, ClNCS and NCCNS were obtained from calculations using the B3LYP, CCSD(T) and

produced Cr(CO)5(2-MeTHF) by isocyanogen, CNCN. The IR spectra are interpreted in terms of the formation of an isonitrile and a nitrile complex, Cr(CO)5(CNCN) and Cr(CO)5(NCNC). A detailed study of the IR and Raman spectra of Cr(CO)5(CNCN), which was formed in large excess, reveals that the coordinating CN group of CNCN has coordinating and vibrational properties almost identical to those of the CO ligands
Isocyanogen, CNCN, has been produced by pyrolysis of N-cyano-2,3-diphenyl-cyclopropeneimine. The molecule was identified by high-resolution infrared and millimeter wave spectroscopy.
