Methanone, [1,1':4',1''-terphenyl]-2',3'-diylbis[phenyl-], also known as 4,4'-(2,2'-dimethano[1,1'-biphenyl]-3,3'-diyl)dibenzaldehyde, is a complex organic compound with the molecular formula C25H18O2. It is a derivative of terphenyl, a type of polycyclic aromatic hydrocarbon, and features a central methanone (ketone) group connected to two phenyl rings through a dimethano bridge. Methanone, [1,1':4',1''-terphenyl]-2',3'-diylbis[phenyl- is characterized by its rigid, planar structure and is often used in the synthesis of various organic compounds, such as polymers and pharmaceuticals, due to its unique electronic and steric properties.

6807-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6807-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,0 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6807-33:
(6*6)+(5*8)+(4*0)+(3*7)+(2*3)+(1*3)=106
106 % 10 = 6
So 6807-33-6 is a valid CAS Registry Number.

Synthesis of stable 7-phosphanorbornadiene P-oxides

Matsumoto, Kiyoshi,Hashimoto, Shiro

, p. 201 - 203 (2007/10/02)

Nonbenzo-annelated stable 7-phosphanorbornadiene P-oxides have been prepared for the first time by the high pressure Diels-Alder reaction of 1,2,3,4,5-pentaphenylphosphole oxide with diaroylacetylenes.The P-oxides decompose around 100 deg C to give the 1,

Chemilumineszenz- und Oxidationsreactionen von Phthaloylperoxid und verwandten Verbindungen.

Gundermann, Karl-Dietrich,Steinfatt, Manfred,Witt, Peter,Paetz, Christian,Poeppel, Karl-Ludwig

, p. 2801 - 2822 (2007/10/02)

Phthaloylperoxid (PPO) und 4,5-Dichlorphthaloylperoxid ergeben mit fluoreszenzfaehigen aromatischen Kohlenwasserstoffen wie 9,10-Diphenylanthracen (DPA), 9,10-Bis(phenylethinyl)anthracen, Pyren, Perylen, aber auch heterocyclischen Verbindungen wie 1,3-Diphenylbenzofuran (9), Luminol oder Fluorescein Chemilumineszenz, die Quantenausbeuten bis 1E-3 Einstein/mol erreichen kann, wenn Phthalsaeureester als Loesungsmittel eingesetzt werden.Die Chemilumineszenz wird durch Sauerstoff hinsichtlich der Maximalintensitaet gesteigert, hinsichtlich der Lichtausbeute auf etwa 80percent verringert.Da bei Derivaten des 1,3-Diphenyl-benzofurans sowohl Chemilumineszenz, als auch Bildung der entsprechenden "Photooxdationsprodukte" (bei 9: o-Dibenzoylbenzol) beobachtet wurde, wird die Moeglichkeit der Bildung von Singulett-Sauerstoff aus PPO diskutiert.Die Bildung von Phthalsaeure-halbestern aus PPO und Olefinen anstelle des Auftretens von Hydroperoxiden wird ueber die thermodynamisch moegliche intermediaere Bildung von Benzocyclobutendion erklaert und ist kein grundsaetzlicher Widerspruch gegen das Auftreten von Singulett-Sauerstoff bei PPO-Reaktionen.
