59303-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59303-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,3,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59303-19:
(7*5)+(6*9)+(5*3)+(4*0)+(3*3)+(2*1)+(1*9)=124
124 % 10 = 4
So 59303-19-4 is a valid CAS Registry Number.

Practical: In situ -generation of phosphinite ligands for palladium-catalyzed carbonylation of (hetero)aryl bromides forming esters

Wang, Lin,Neumann, Helfried,Spannenberg, Anke,Beller, Matthias

supporting information, p. 7469 - 7472 (2017/07/12)

An effective method for alkoxycarbonylation of (hetero)aryl bromides is developed in the presence of in situ-generated phosphinite ligands tBu2POR (R = nBu, nPr, Et or Me). For this purpose commercially available tBu2PCl was used as the pre-ligand in the presence of different alcohols. For the first time cross coupling reactions with two alcohols-one generating the ligand, the other used as substrate-were developed. Through this method, ligand optimization can be performed in a more efficient manner and the desired products could be obtained with good yields and selectivity.

Synthesis of 2-thiophenecarboxylic and 2,5-thiophenedicarboxylic acid esters via the reaction of thiophenes with the CCl4-ROH reagent in the presence of vanadium, iron, and molybdenum catalysts

Khusnutdinov,Shchadneva,Baiguzina,Mukminov,Mayakova,Smirnov,Dzhemilev

experimental part, p. 471 - 478 (2010/03/31)

2-Thiophenecarboxylic and 2,5-thiohenedicarboxylic acid esters were synthesized via the reaction of thiophene with the CCl4-ROH-catalyst system, with a total yield of 44-85%. A possible reaction scheme includes the successive steps of alkylation of thiophene with carbon tetrachloride, leading to 2-trichloromethylthiophene, and alcoholysis of the product giving the corresponding 2-thiophenecarboxylate. The best catalysts for this reaction are VO(acac)2, Fe(acac)3, and Mo(CO)6.
