Reaction of nitrogen atoms with sulfur monoxide

Synthesis of nitrogen and sulfur macrocycles with cis exogenous oxygen and sulfur donor atoms.

A series of new N4 and N8 macrocycles has been prepared, that includes cis-exogenous O2, S2 and S/O atoms to allow chelation to a metal external to the macrocyclic ring. We found that thioamide units within the macrocycles were unstable to attack by secondary amines and thus alkylated precursors containing only tertiary amines could lead to exogenous-S2 macrocycles. Cyclisation of alkylated tet...

Sodium or cesium-assisted nitrogen monoxide reaction with InP(110) at ambient temperature

Rotational study of carbon monoxide solvated with helium atoms.

High resolution microwave and millimeter-wave spectra of HeN-CO clusters with N up to 10, produced in a molecular expansion, were observed. Two series of J = 1-0 transitions were detected, which correspond to the a-type and b-type J = 1-0 transitions of He1-CO. The B rotational constant initially decreases with N and reaches a minimum at N = 3. Its subsequent rise indicates the transition from ...

I he Reaction of Sulfur with Dilithio

The sequential reaction of selected polycyclic aromatic hydrocarbons with butyllithium/TMEDA/ hexane and sulfur allows preparation of ring-fused dithiins, dithioles, and thiophenes. In this manner, phenanthrene has been converted to phenanthro[4,5-~de][1,2]dithiin and phenanthro[l,IOc~-1,2dithiole. Yellow crystals of the dithiin form inoC2/c (#15) space group .with < = 4, a = 13.537(3) A, b = 8...
