66680-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66680-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66680-81:
(7*6)+(6*6)+(5*6)+(4*8)+(3*0)+(2*8)+(1*1)=157
157 % 10 = 7
So 66680-81-7 is a valid CAS Registry Number.

An efficient metal-free oxidative esterification and amination of benzyl C-H bond

Liu, Saiwen,Chen, Ru,He, Guowen,Zhang, Jin

, (2020/04/09)

An esterification and amination of benzylic C-H bonds was developed by using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) under metal- and iodide-free conditions. Both carboxylic acids and amines could be used as ideal coupling partners for the oxidati

Making Carbonyls of Amides Nucleophilic and Hydroxyls of Alcohols Electrophilic Mediated by SO2F2 for Synthesis of Esters from Amides

Fang, Wan-Yin,Zha, Gao-Feng,Qin, Hua-Li

supporting information, p. 8657 - 8661 (2019/10/17)

We discovered that with the promotion of sulfuryl fluoride, the carbonyl groups of amides performed as nucleophiles while the hydroxyl groups of alcohols were activated to functionalize as electrophiles. This study displayed that the amide C-N bonds could be easily cleaved with delicate nucleophiles to form the ester C-O bonds at room temperature without using transition metals. The broad substrate scope and excellent functional group compatibility were proved with 44 examples in up to 99% yields.

Method for preparing formate-type compound

-

Paragraph 0039; 0047; 0048, (2018/07/30)

The invention discloses a method for preparing a formate-type compound. The method comprises the following steps of: adopting an alcohol-type compound and 1,3-dihydroxyacetone as reaction raw materials, and under the existence of a composite catalyst and an oxidant, reacting for 2-48 hours in a reaction medium in a reactor at a reaction temperature of 25-100 DEG C so as to obtain the formate-typecompound. The method disclosed by the invention is simple, and is mild in reaction condition, and by the method, a target product can be obtained by low cost and high yield; the used catalyst has highcatalytic activity, and is easily separated from a reaction system to be repeatedly used; the whole process is environment-friendly, and the reaction raw material (1,3-dihydroxyacetone) is easily converted from a side product (glycerol) of biodiesel, so that the utilization of the glycerol is promoted.
