75245-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75245-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,4 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75245-67:
(7*7)+(6*5)+(5*2)+(4*4)+(3*5)+(2*6)+(1*7)=139
139 % 10 = 9
So 75245-67-9 is a valid CAS Registry Number.

Development of a Scalable Lanthanide Halide/Quaternary Ammonium Salt System for the Nucleophilic Addition of Grignard Reagents to Carbonyl Groups and Application to the Synthesis of a Remdesivir Intermediate

Brak, Katrien,Bremner, W. Stacy,Brown, Angela M.,Chtchemelinine, Andrei,Heumann, Lars,Kerschen, James A.,Stevens, Andrew C.,Subotkowski, Witold,Vieira, Tiago,Wolfe, Lydia C.,Xu, Boran,Yu, Chia-Yun

This manuscript describes the development and implementation of a scalable additive system, consisting of a lanthanide salt and a solubilizing quaternary ammonium salt, to improve the yield and robustness of the addition of an organomagnesium reagent to a

Solutions of anhydrous lanthanide salts and its preparation

-

, (2008/06/13)

The present invention relates to anhydrous solutions of MX 3 €¢z LiA in a solvent, wherein M is a lanthanide including lanthanum, or yttrium or indium; z > 0; and X and A are independently or both monovalent anions, preferably Cl, Br or I. The solution is readily prepared by dissolving or suspending MX 3 or its hydrate and z equiv LiA in water or hydrophilic solvents, or mixtures thereof, removing the solvent under vacuum and dissolving the resulting powder in another solvent. The solution of MX 3 €¢z LiA can advantageously be used e.g. in addition reactions of Grignard reagents to ketones and imines. Even the catalytic use of MX 3 €¢z LiA is possible. Also claimed are a method for preparing the anhydrous solutions, the use of such solution in a chemical reaction and chemical compositions MX 3 €¢z LiA, with M, z, X and A as indicated above.

Some uses of mischmetall in organic synthesis

Lannou, Marie-Isabelle,Hélion, Florence,Namy, Jean-Louis

, p. 10551 - 10565 (2007/10/03)

Mischmetall, an alloy of the light lanthanides, has been used in a variety of organic reactions, either as a coreductant in samarium(II)-mediated reactions (Barbier and Grignard-type reactions, pinacolic coupling reactions) or as the promoter of Reformatsky-type reactions. It has been also employed as the starting material for easy syntheses of lanthanide trihalides, the reactivity of which has been explored in Imamoto and Luche-Fukuzawa reactions and in Mukaiyama aldol reactions.
