76280-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76280-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,8 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76280-42:
(7*7)+(6*6)+(5*2)+(4*8)+(3*0)+(2*4)+(1*2)=137
137 % 10 = 7
So 76280-42-7 is a valid CAS Registry Number.

Syntheses, structures, and thermolyses of pentacoordinate 1,2-oxastibetanes: Potential intermediates in the reactions of stibonium ylides with carbonyl compounds

Uchiyama, Yosuke,Kano, Naokazu,Kawashima, Takayuki

, p. 659 - 670 (2006)

Pentacoordinate 1,2-oxastibetanes 14a-d, which are formal [2 + 2]-cycloadducts of the reactions of stibonium ylides with carbonyl compounds, were successfully synthesized by the reactions of the corresponding bromo-2-hydroxyalkylstiboraiies with NaH. The

Z-trifluoromethyl thioenol ethers, enol ethers, and enamines; reactivity towards organolithium reagents

Begue, Jean-Pierre,Bonnet-Delpon, Daniele,Rock, Michael H.

, p. 171 - 174 (1996)

Trifluoromethyl enol ethers and thioenol ethers conjugated with an unsaturation in the β-position undergo addition/elimination reactions with organolithium reagents to yield the corresponding trifluoromethyl alkenes while preserving the geometry of the do

Synthesis of (Z)-α-Trifluoromethyl Alkenyl Triflate: A Scaffold for Diverse Trifluoromethylated Species

Zhao, Yilong,Zhou, Yuhan,Liu, Juan,Yang, Dongmei,Tao, Liang,Liu, Yang,Dong, Xiaoliang,Liu, Jianhui,Qu, Jingping

, p. 4797 - 4806 (2016/07/06)

An efficient method for the synthesis of (Z)-selective α-trifluoromethyl alkenyl triflates is described. As an important fluorinated building block, it is utilized successfully for the synthesis of various trifluoromethyl derivatives such as diarylethylen

Pd-carbene migratory insertion: Application to the synthesis of trifluoromethylated alkenes and dienes

Wang, Xi,Xu, Yan,Deng, Yifan,Zhou, Yujing,Feng, Jiajie,Ji, Guojing,Zhang, Yan,Wang, Jianbo

supporting information, p. 961 - 965 (2014/02/14)

Pd-catalyzed cross-coupling of halides with CF3-substituted diazo compounds or N-tosylhydrazones has been explored for the synthesis of CF3-substituted alkenes and 1,3-butadienes. Pd-carbene migratory insertion plays the key role in these transformations. Copyright

One-pot multistep synthesis of trisubstituted alkenes from N -tosylhydrazones and alcohols

Sha, Qiang,Wei, Yunyang

supporting information, p. 2353 - 2361 (2014/11/08)

A one-pot procedure for the synthesis of trisubstituted alkenes from N-tosylhydrazones and alcohols is reported. This procedure combines the aerobic oxidation reaction and Wittig reaction in one pot, which avoids using of environmentally toxic oxidants and isolation of the intermediates. The simple procedure makes it very attractive for the synthesis of trisubstituted alkenes when alcohols are used as starting materials. A variety of trisubstituted alkenes as well as trifluoromethyl-substituted alkenes were obtained in moderate to good yields (up to 84%) with good E-selectivity (up to 99%).
