43133-31-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 43133-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,1,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 43133-31:
(7*4)+(6*3)+(5*1)+(4*3)+(3*3)+(2*3)+(1*1)=79
79 % 10 = 9
So 43133-31-9 is a valid CAS Registry Number.

Highly efficient Pd/tetraphosphine catalytic system for copper-free sonogashira reactions of aryl bromides with terminal alkynes

Yi, Tao,Mo, Min,Fu, Hai-Yan,Li, Rui-Xiang,Chen, Hua,Li, Xian-Jun

, p. 594 - 600 (2012)

In this study, an easily synthesized polydentate ligand N,N,N',N'-tetra(diphenylphosphinomethyl)-1,2-ethylenediamine (1) in combination with [Pd(C3H5)Cl]2 was found to be an active catalyst in copper-free Sonogashira reactions. Most substrates, including steric hindered phenyl bromides and heteroaryl bromides, could couple efficiently with terminal alkynes in the presence of low catalyst loading (0.1 mol%) and this catalytic system showed excellent functional group tolerance. The influence of water in this system was also preliminarily investigated via 31P NMR in situ; that is, appropriate water favors the reaction while excess hindered this reaction.
