24931-66-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24931-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,9,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24931-66:
(7*2)+(6*4)+(5*9)+(4*3)+(3*1)+(2*6)+(1*6)=116
116 % 10 = 6
So 24931-66-6 is a valid CAS Registry Number.

ASYMMETRIC INDUCTION IN THE PALLADIUM-CATALYZED SULFONYLATION OF ALLYLIC SULFINATES AND ACETATES WITH CHIRAL PHOSPHINE LIGANDS

Hiroi, Kunio,Makino, Kunitaka

, p. 617 - 620 (1986)

Treatment of allylic (+/-)-p-toluenesulfinates with tetrakis-(triphenylphosphine) palladium in the presence of chiral phosphine ligands underwent allylic sulfinate-sulfone rearrangements to give the corresponding optically active allylic sulfones in high

"Syn-Effect" in the Desilylation Reaction of γ-Silylated Allylic and Vinylic Sulfones

Guha, Samar Kumar,Ukaji, Yutaka,Inomata, Katsuhiko

, p. 1158 - 1159 (2007/10/03)

The desilylation reaction of γ-silylated allylic sulfones was found to proceed through γ-silylated (E)-vinylic sulfones to afford the corresponding allylic sulfones by treatment with DBU and H2O. The Z/ E ratio of the resulting allylic sulfones varied according to the γ-substituents of the γ-silylated sulfones. This stereo-chemical outcome was rationalized by "syn-effect".

INDUCTION PAR LA LUMIERE DE L'OXYDATION DES COMPLEXES Η3-ALLYLPALLADIUM PAR L'OXYGENE MOLECULAIRE

Muzart, J.,Pale, P.,Pete, J.P.,Riahi, A.

, p. 731 - 739 (2007/10/02)

Irradiation at λ=366 nm of oxygenated solutions of η3-allylpalladium complexes leads to unsaturated carbonyl compounds.Substitution of the η3-allyl ligand by an electron withdrawing group could induce a regioselective oxidation of the allylic position farthest from this group.The efficiency of these reactions is sensible to the nature of the solvent.
