1758-10-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1758-10-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1758-10:
(6*1)+(5*7)+(4*5)+(3*8)+(2*1)+(1*0)=87
87 % 10 = 7
So 1758-10-7 is a valid CAS Registry Number.

Investigating the microwave-accelerated Claisen rearrangement of allyl aryl ethers: Scope of the catalysts, solvents, temperatures, and substrates

Hui, Zi,Jiang, Songwei,Qi, Xiang,Ye, Xiang-Yang,Xie, Tian

supporting information, (2020/05/18)

The microwave-accelerated Claisen rearrangement of allyl aryl ethers was investigated, in order to gain insight into the scope of the catalysts, solvents, temperatures, and substrates. Among the catalysts examined, phosphomolybdic acid (PMA) was found to greatly accelerate the reaction in NMP, at temperatures ranging from 220 to 300 °C. This method was found to be useful for preparing several intermediates previously reported in the literature using precious metal catalysts such as Au(I), Ag(I), and Pt(II). Additionally, substrates bearing bromo and nitro groups on the aryl portion required careful tailoring of the reaction conditions to avoid complex product profiles.

Green Organocatalytic Synthesis of Dihydrobenzofurans by Oxidation-Cyclization of Allylphenols

supporting information, p. 4254 - 4260 (2017/09/12)

A green and cheap protocol for the synthesis of dihydrobenzofurans via an organocatalytic oxidation of o -allylphenols is presented. The use of 2,2,2-trifluoroacetophenone and H 2 O 2 as the oxidation system, leads to a highly useful synthetic method, where a variety of substituted o -allylphenols were cyclized in high yields..

An efficient palladium-catalyzed synthesis of cinnamyl ethers from aromatic halides, phenols, and allylic chloride

Wang, Wei,Zhou, Rong,Jiang, Zhi-Jie,Wang, Kun,Fu, Hai-Yan,Zheng, Xue-Li,Chen, Hua,Li, Rui-Xiang

supporting information, p. 616 - 622 (2014/05/20)

A one-pot, two-step catalytic protocol for the preparation of cinnamyl ethers from simple and readily available aryl halides, phenols and allyl chloride is reported for the first time. This simple and highly efficient palladium nanoparticles catalytic system shows good regio- and stereoselectivities and affords the desired products in good to high yields (49-85%) from aryl iodides. Furthermore, less reactive aryl bromides can also give the cinnamyl ethers in moderate yields (24-72%).
