3009-50-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3009-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,0 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3009-50:
(6*3)+(5*0)+(4*0)+(3*9)+(2*5)+(1*0)=55
55 % 10 = 5
So 3009-50-5 is a valid CAS Registry Number.

Mechanism of Azo Coupling Reactions: Part XXXVI. The Relationship between the Structure and the Catalytic Activity of Anionic Phase-Transfer Catalysts in Azo Coupling Reactions

Iwamoto, Hidetoshi,Kobayashi, Hiroshi,Murer, Pius,Sonoda, Takaaki,Zollinger, Heinrich

, p. 2590 - 2602 (2007/10/02)

A series of 15 sodium arenesulfonates containing alkyl, hydroxyl or methoxyl groups was investigated for the phase-transfer catalysis of the azo coupling reaction of the 4-methoxybenzenediazonium ion (1) with 1,3,5-trimethoxybenzene (2) in a dichloromethane/water two-phase system, in which the yields, initial reaction rates and influence of the decomposition of the diazonium ion 1 were measured.The influence of counter anions on the partition coefficient (α) for the diazonium ion 1 in a dichloromethane/water system, and the effects of the solvent polarity and structure of counter anions on the reaction rates of the azo coupling of the diazonium ion 1 with N,N-dimethylaniline (4) and 1,3,5-trimethoxybenzene (2) in organic solvents and in dichloromethane/water system, were investigated.The symmetrical structure of the tetrakisborate (TFPB) anion was proved to be an essential factor regarding the remarkably high α for the diazonium ion 1 ion-paired with TFPB.The looseness and tightness of ion pairs of highly desolvated diazonium ion 1 in a nonpolar organic media is one of the most significant factors concerning the reactivity of the diazonium ion 1 in a rate-limiting azo coupling with 4.In a reaction of the diazonium ion 1 with 2 in a dichloromethane/water system, however, the amount of saturated water and/or additives in the dichloromethane phase, which serves as a base for the rate-limiting deprotonation, becomes the most influential factor for an effective azo coupling reaction under phase-transfer catalysis conditions.

Photochemical Decomposition of 4-Arylazo- and 4-Arylazoxy-N,N-dialkylaniline N-Oxides

Albini, Angelo,Fasani, Elisa,Moroni, Micaela,Pietra, Silvio

, p. 1439 - 1444 (2007/10/02)

The 4-aryl-N,N-dialkylaniline N-oxides (1a-c) decompose on u.v. irradiation in aprotic solvents, undergoing deoxygenation as well as intramolecular hydrogen abstraction, to give amides and dealkylated products.The latter process is more important for the diethyl derivative (1b) (photoCope elimination).Visible irradiation is ineffective.The 4-arylazoxy-N,N-dialkylaniline N-oxides (2a-d) undergo photochemical deoxygenation from the amino group (major process) as well as from the azo group.The mechanism of these photoprocesses is discussed in general and in relation to the possible involvement of these N-oxide derivatives in photofading of the related azo dyes.

Mechanisms of Diazo Coupling Reactions. Part XXXI. Aminoazo Formation in the Diazo Coupling of N,N-Dimethylaniline and m-Toluidine with p-Methoxybenzenediazonium Tetrafluoroborate in Acetonitrile

Penton, John R.,Zollinger, Heinrich

, p. 1728 - 1738 (2007/10/02)

In the title reactions it is shown that aminoazo formation does not occur by direct attack of diazonium ion at C-atom.Initial attack is at N-atom, but proton loss from the ?N-complex formed is relatively slow.Hence, at low amine concentration t
