940866-95-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 940866-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,8,6 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 940866-95:
(8*9)+(7*4)+(6*0)+(5*8)+(4*6)+(3*6)+(2*9)+(1*5)=205
205 % 10 = 5
So 940866-95-5 is a valid CAS Registry Number.

Method for constructing C-N bond through insertion reaction of non-metal catalyzed sulfur ylide and aromatic amine and application

-

Paragraph 0012, (2020/10/20)

The invention relates to a method for constructing a C-N bond through an insertion reaction of non-metal catalyzed sulfur ylide and aromatic amine and application. According to the method, water is used as a reaction solvent, and sulfur ylide is subjected to an N-H insertion reaction under mild conditions to construct a C-N bond. As a way of constructing a C-N bond, the method overcomes the defects of traditional use of metal catalysts or oxidants. On the basis of the method, various alpha-amino acid ester derivatives can be obtained by using different aromatic amines as substrates. Accordingto the method, the raw materials are easy to obtain, use of a metal catalyst, an oxidizing agent and an organic solvent is avoided, and the method is a mild, effective and environment-friendly methodfor preparing the alpha-amino acid ester and has wide application prospects.

Carbene X[sbnd]H bond insertions catalyzed by copper(I) macrocyclic pyridine-containing ligand (PcL) complexes

Tseberlidis, Giorgio,Caselli, Alessandro,Vicente, Rubén

supporting information, p. 1 - 5 (2017/03/01)

A catalytic system comprising copper(I) and macrocyclic pyridine-containing ligands (Pc-L) proves capable of promoting carbene Si[sbnd]H bond insertions using diazo compounds as the carbene source. This catalytic system showed broad scope and a remarkable robustness as indicated by high TON numbers (up to 30000). Moreover, the use of enynones as carbene sources proved also feasible in hydrosilane insertion using this catalytic system. Finally, the insertion in O[sbnd]H and N[sbnd]H bonds of phenols and anilines, respectively, has been also demonstrated.
