881851-79-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 881851-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,8,5 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 881851-79:
(8*8)+(7*8)+(6*1)+(5*8)+(4*5)+(3*1)+(2*7)+(1*9)=212
212 % 10 = 2
So 881851-79-2 is a valid CAS Registry Number.

Pd-Catalyzed Stereoselective 1,2-Aryboration of Alkenylarenes

Zhang, Penglin,Xing, Mimi,Guan, Qitao,Zhang, Jinguo,Zhao, Qian,Zhang, Chun

supporting information, p. 8106 - 8109 (2019/10/10)

The palladium-catalyzed highly regio- and diastereoselective arylboration of alkenylarenes has been developed. This chemistry afforded the benzylic boronic esters with a broad substrate scope, which are valuable synthetic intermediates for organic synthes

Asymmetric transfer hydrogenation of α,β-unsaturated, α-tosyloxy and α-substituted ketones

Peach, Philip,Cross, David J.,Kenny, Jennifer A.,Mann, Inderjit,Houson, Ian,Campbell, Lynne,Walsgrove, Tim,Wills, Martin

, p. 1864 - 1876 (2007/10/03)

Asymmetric transfer hydrogenation of cyclic and acyclic α,β-unsaturated ketones catalysed by η6-p-cymene/ ruthenium(II) and η5-pentamethylcyclopentadienyl/rhodium(III) complexes have been investigated. Cyclic α,β-unsaturated ketones appeared to be more suitable substrates for the synthesis of enantiomerically pure allylic alcohols than do acyclic α,β-unsaturated ketones. A proposed mechanism for the formation of 4-phenyl-[1,3]-dioxolan-2-one from α-tosyloxy- and halo-substituted acetophenones is discussed. The results of further investigations into the reduction of a range of α- tosyloxyacetophenones and the dynamic kinetic resolution of α-substituted ketones is presented.
