Recommanded Product: 88-99-3, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 88-99-3, Name is Pathalic acid, SMILES is O=C(O)C1=CC=CC=C1C(O)=O, belongs to phthalazine compound. In a article, author is Hoj, Martin, introduce new discover of the category.
1-Azidophthalazine 9A is generated in trace amount by mild FVT of tetrazolo[5,1-a]phthalazine 9T and is observable by its absorption at 2121 cm(-1) in the Ar matrix IR spectrum. Ar matrix photolysis of 9T/9A at 254 nm causes ring opening to generate two conformers of (o-cyanophenyl)diazomethane 11 (2079 and 2075 cm(-1)), followed by (o-cyanophenyl)carbene (3)12, cyanocycloheptatetraene 13, and finally cyano(phenyl)carbene (3)14 as evaluated by IR spectroscopy. The two carbenes (3)12 and (3)14 were observed by ESR spectroscopy (D vertical bar hc = 0.5078, E vertical bar hc = 0.0236 and D vertical bar hc = 0.6488, E vertical bar hc = 0.0195 cm(-1), respectively). The rearrangement of 12 reversible arrow 13 reversible arrow 14 constitutes a carbene carbene-rearrangement. 1-Phthalazinylnitrene (3)10 is observed by means of its UV-vis spectrum in Ar matrix following FVT of 9 above 550 degrees C. Rearrangement to cyanophenylcarbenes also takes place on FVT of 9 as evidenced by observation of the products of ring contraction, viz., fulvenallenes and ethynylcyclopentadienes 16-18. Thus the overall rearrangement 10 -> 11 -> 12 reversible arrow 13 reversible arrow 14 can be formulated.
