76583-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76583-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,8 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76583-99:
(7*7)+(6*6)+(5*5)+(4*8)+(3*3)+(2*9)+(1*9)=178
178 % 10 = 8
So 76583-99-8 is a valid CAS Registry Number.

Radical C(sp3)-H alkenylation, alkynylation and allylation of ethers and amides enabled by photocatalysis

Paul, Subhasis,Guin, Joyram

supporting information, p. 2530 - 2534 (2017/07/17)

An efficient radical addition/elimination reaction that enables selective incorporation of alkenyl, alkynyl and allyl functional groups into the C(sp3)-H bond under green reaction conditions is developed. The process is based on the catalytic formation of α-alkoxyl/α-amidyl radicals via the homolytic activation of the C(sp3)-H bond of ethers/amides with a catalytic amount of diarylketone in the presence of a household fluorescent light bulb. This simple reaction protocol features good functional group tolerance, scalability, convenient reagents and operating systems. Synthetic application of the method has been demonstrated via the preparation of natural products and different valuable synthones.

Regio- and stereoselective Au(I)-catalyzed intermolecular hydroalkoxylation of aryl allenes

Cui, Dong-Mei,Yu, Ke-Rui,Zhang, Chen

scheme or table, p. 1103 - 1106 (2009/09/30)

In the presence of a catalytic amount of Ph3PAuNO3 and H2SO4, the hydroalkoxylation of allenes with alcohols has been shown to proceed smoothly and give allylic ethers in good yields and high regio- and stereoselectivity. Georg Thieme Verlag Stuttgart.

Palladium-catalyzed coupling of alkynes with alcohols and carboxylic acids

Zhang, Weijiang,Haight, Anthony R.,Hsu, Margaret C.

, p. 6575 - 6578 (2007/10/03)

The palladium-catalyzed coupling of alkynes with alcohols and carboxylic acids to give allylic ethers and esters has been achieved. With phenols, these conditions furnish the C-alkylation products.
