1,3-Dithiol-2-ylidene derivatives containing bis(ethynylpyridine) units were synthesized using a Pd-catalyzed reaction of the corresponding dibromide. X-Ray crystal analysis revealed unique crystal structures depending on the aromatic groups. The absorption spectra and redox properties indicated int
## Abstract The inhibiting activity of poly (2βmethylβ5βethynylpyridine) (PEP) has been studied in the cumene oxidation reaction initiated by azobisisobutyronitrile at 55β65Β°C. According to the kinetic data the reaction between RO~2~ radical and PEP is irreversible. About 12% of the most active mac
