Bromination regiochemistry of 4-Phenyl-2,7-dichloro-2H-chryseno-[6,5-e][1,2]phosphinine 2-oxide
摘要:
Regioselective bromination of 4-phenyl-2,7-dichloro-2H-chryseno[6,5-e][1,2]phosphinine 2-oxide proceeded in the position 3 with the formation of 3-bromo-4-phenyl-2,7-dichloro-2H-chryseno[6,5-e][1,2] phosphinine 2-oxide; the structure of its 2-tert-butylamino derivative was established by XRD analysis and correlation spectroscopy.
Reactions in the chrysenequinone–phenylacetylene–phosphorus trichloride system: formation and crystal structure of 2,7-dichloro-2-oxo-4-phenylbenzo[o]-1,2-oxaphosphatriphenylene
摘要:
The reaction of chrysenequinone with phenylacetylene in the presence of phosphorus trichloride leads to the formation of a new phosphorus heterocycle, 2,7-dichloro-2-oxo-4-phenylbenzo[o]-1,2-oxaphosphatriphenylene, whose structure was established by NMR spectroscopy and single crystal X-ray diffraction.
