167556-11-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167556-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,5,5 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 167556-11:
(8*1)+(7*6)+(6*7)+(5*5)+(4*5)+(3*6)+(2*1)+(1*1)=158
158 % 10 = 8
So 167556-11-8 is a valid CAS Registry Number.

Thermolysis of selenophene 1,1-dioxides

Umezawa, Takashi,Matsui, Tomoki,Sugihara, Yoshiaki,Ishii, Akihiko,Nakayama, Juzo

, p. 61 - 69 (2007/10/03)

Selenophene 1,1-dioxides are thermally far labile than the corresponding thiophene 1,1-dioxides. Even heavily substituted tetraphenylselenophene 1,1-dioxide (1a) decomposed, by a process not involving cyclodimerization, when heated above its melting point or heated in refluxing toluene. Thus, the thermolysis of la in refluxing toluene afforded tetraphenylselenophene (2a, 6%), tetraphenylfuran (3a, 71%), (Z)-l,2,3,4-tetraphenyl-2-butene-l,4-dione (Z-4a, 19%), (E)-1,2,3,4-tetraphenyl-2-butene-1,4-dione (E-4a, 4%), SeO2 (23%), and Se (22%), while that of the neat sample gave 2a (5%), Z-4a (78%), E-4a (17%), SeO2 (17%), and Se (29%). Similar results were also obtained on thermolyses of a series of selenophene 1,1-dioxides. The experimental observations (influence of solvents, oxygen, and additive such as diene to the decomposition rate and the presence of induction period) revealed that the mechanism of the decomposition is highly complex. A tentative mechanism that can explain the observed products is presented.

Oxidation of Aromatic Compounds. IV. Oxidation of Symmetrical Diarylacetylenes in the CF3COOH-CH2Cl2-PbO2 System. A New One-Pot Synthesis of 1,2,3,4-Tetraaryl-2-butene-1,4-diones

Rudenko, A. P.,Vasil'ev, A. V.

, p. 1360 - 1379 (2007/10/03)

Oxidation of symmetrical diarylacetylenes in the CF3COOH-CH2Cl2-PbO2 system (0-20 deg C, 1-3 h) yields 1,2,3,4-tetraaryl-2-butene-1,4-diones.According to (1)H NMR and GC-MS data the compounds synthesized have Z configuration.

Oxidation of Tetraarylselenophenes and Benzoselenophene with m-Chloroperbenzoic Acid

Nakayama, Juzo,Matsui, Tomoki,Sato, Noriko

, p. 485 - 486 (2007/10/03)

Oxidation of tetraarylselenophenes with m-chloroperbenzoic acid produces cis-1,2-diaroyl-1,2-diarylethylenes and SeO2 as the principal product, while the oxidation of benzoselenophene affords benzoselenophene 1-oxide.
