80684-99-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80684-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80684-99:
(7*8)+(6*0)+(5*6)+(4*8)+(3*4)+(2*9)+(1*9)=157
157 % 10 = 7
So 80684-99-7 is a valid CAS Registry Number.

Nickel-Catalyzed Enantioconvergent Reductive Hydroalkylation of Olefins with α-Heteroatom Phosphorus or Sulfur Alkyl Electrophiles

Fu, Yao,He, Shi-Jiang,Li, Yan,Lu, Xi,Wang, Jia-Wang,Wang, Xiao-Xu,Xu, Zhe-Yuan

supporting information, (2020/01/22)

Substantial advances in enantioconvergent C(sp3)-C(sp3) bond formation reactions have been made in recent years through the use of transition-metal-catalyzed cross-coupling reactions of racemic secondary alkyl electrophiles with organometallic reagents. Herein, we report a general process for the asymmetric construction of alkyl-alkyl bonds adjacent to heteroatoms, namely, a nickel-catalyzed enantioconvergent reductive hydroalkylation of olefins with α-heteroatom phosphorus or sulfur alkyl electrophiles. Including the use of readily available olefins, this reaction has considerable advantages, such as mild reaction conditions, a broad substrate scope, and good functional group compatibility, making it a desirable alternative to traditional electrophile-nucleophile cross-coupling reactions.

Studies on Chiral Organo-Sulfur Compounds. II. Stereochemistry of Thermal Chiral Allyl Sulfinate-Sulfone Rearrangements

Hiroi, Kunio,Kitayama, Ryuichi,Sato, Shuko

, p. 2628 - 2638 (2007/10/02)

A highly efficient and general synthetic route to optically active sulfinates by the stereospecific boron trifluoride etherate-catalyzed esterification of sulfinamides was developed.Dramatic solvent effects were observed in the thermal transformation of allyl sulfinate derivatives to sulfones.Heating of chiral trans- and cis-allyl sulfinates, (S)-(-)-3a,c,e and (S)-(-)-3b,d,f, in N,N-dimethylformamide at 90-120 deg C provided chiral sulfones (S)-(+)- and (R)-(-)-5,6,7 in good yields, respectively, with exceedingly high stereospecificity. Keywords - asymmetric transfer; stereospecificity; chiral allyl sulfinate; chiral allyl sulfone; boron trifluoride etherate; thermolysis

Optical Stability of Carbanions Derived from Sulphoximides and Sulphilimines

Annunziata, Rita,Cinquini, Mauro,Colonna, Stefano,Cozzi, Franco

, p. 1005 - 1006 (2007/10/02)

Pairs of diastereomeric sulphoximides and sulphilimines of known absolute configuration have been converted into the corresponding carbanions, which have a definite optical stability.
