96256-53-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 96256-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,2,5 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 96256-53:
(7*9)+(6*6)+(5*2)+(4*5)+(3*6)+(2*5)+(1*3)=160
160 % 10 = 0
So 96256-53-0 is a valid CAS Registry Number.

Use of a Traceless Activating and Directing Group for the Construction of Trifluoromethylpyrazoles: One-Pot Transformation of Nitroolefins and Trifluorodiazoethane

Chen, Zhen,Zheng, Yan,Ma, Jun-An

supporting information, p. 4569 - 4574 (2017/04/11)

We disclose an efficient one-pot transformation of trifluorodiazoethane and higher perfluorinated homologues with various nitroolefins. This method takes advantage of the nitro group as a traceless activating and directing group (TADG) that is released in the aromatization step to produce 4-substituted 3-perfluoroalkyl pyrazoles with complete regioselectivity. The potential of this method is further demonstrated by the synthesis of penthiopyrad.

Pyrazole-3/5-carboxylic acids from 3/5-trifluoromethyl NH-pyrazoles

Ermolenko, Mikhail S.,Guillou, Sandrine,Janin, Yves L.

, p. 257 - 263 (2013/01/15)

We report here the transformation of 3/5-trifluoromethylpyrazoles derivative into the corresponding NH-pyrazole-3/5-carboxylic acids. Moreover, from 4- or 5-iodinated-3/5-trifluoromethylpyrazoles building blocks and the use of Suzuki-Miyaura or Negishi reactions followed by the trifluoromethyl hydrolysis, we illustrate short and original accesses to many series of NH-pyrazole-3/5-carboxylic acids otherwise difficult to prepare.

Studies on Organic Fluorine Compounds. XLII. Synthesis and Reactions of Phenyltrifluoromethylacetylenes

Kobayashi, Yoshiro,Yamashita, Toshinori,Takahashi, Katsuhiro,Kuroda, Hisashi,Kumadaki, Itsumaro

, p. 4402 - 4409 (2007/10/02)

Phenyltrifluoromethylacetylene (4a) was synthesized by the pyrolysis of triphenylphosphonium α-(trifluoroacetyl)benzylide (3a), which was easily derived from benzyl halide (1a).This method can be used for the synthesis of 4-substituted-phenyltrifluoromethylacetylenes (4).The 1,3-dipolar reaction of 4 with diazomethane and phenyl azide proceeds readily to give trifluoromethylated pyrazoles and triazoles.Keywords - trifluoromethyl; acetylene; 1,3-dipolar reaction; intramolecular Wittig reaction; trifluoroacetylphosphonium ylide; pyrazole; diazomethane; phenyl azide
