68271-77-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68271-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,7 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68271-77:
(7*6)+(6*8)+(5*2)+(4*7)+(3*1)+(2*7)+(1*7)=152
152 % 10 = 2
So 68271-77-2 is a valid CAS Registry Number.

Transition metal-free Suzuki type cross-coupling reaction for the synthesis of dissymmetric ketones

Jadhav, Sanjay,Rashinkar, Gajanan,Salunkhe, Rajashri,Kumbhar, Arjun

supporting information, p. 3201 - 3204 (2017/07/27)

A simple, efficient and metal-free route for the synthesis of dissymmetric ketones through Suzuki type cross-coupling reaction has been established. This strategy signifies an attractive, cost-effective and operationally convenient tool for the synthesis of a wide range of dissymmetric ketones. Although conventional routes for the synthesis of ketones have been widely used, the potential challenge with these methods is functional group tolerance. The reported metal-free method represents a reaction with moderate functional group tolerance. The procedure is operationally convenient and shows broad substrate scope with good to excellent product yields.

Iron-catalyzed carbonylative Suzuki reactions under atmospheric pressure of carbon monoxide

Zhong, Yanzhen,Han, Wei

supporting information, p. 3874 - 3877 (2014/04/03)

The first highly effective iron-catalyzed carbonylative Suzuki reaction has been developed. Substrates with electron-donating or electron-withdrawing functionality, ortho-substitution, as well as active groups proceeded smoothly, affording desired products in high yields. This protocol is economical, environmentally benign and practical for the synthesis of biaryl ketones. This journal is the Partner Organisations 2014.
