99135-90-7 Usage

General Description

(3R,4R)-(+)-BIS(DIPHENYLPHOSPHINO)PYRROLIDINE is a chiral ligand commonly used in asymmetric catalysis and organic synthesis. It consists of a pyrrolidine ring with two bulky diphenylphosphino groups attached to the nitrogen atom. (3R,4R)-(+)-BIS(DIPHENYLPHOSPHINO)PYRROLIDINE is known for its ability to selectively bind to metal ions, particularly in the formation of transition metal complexes. These complexes are often used as catalysts in various chemical reactions, such as asymmetric hydrogenation and C-C bond forming reactions. The chiral nature of this compound allows for the production of enantiomerically pure products, making it a valuable tool in organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 99135-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,3 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99135-90:
(7*9)+(6*9)+(5*1)+(4*3)+(3*5)+(2*9)+(1*0)=167
167 % 10 = 7
So 99135-90-7 is a valid CAS Registry Number.

Enantioselective Catalysis, 4. Synthesis of N-Substituted (R,R)-3,4-Bis(diphenylphosphino)pyrrolidines. The Use of their Rhodium Complexes for the Asymmetric Hydrogenation of α-(Acylamino)acrylic Acid Derivatives

Nagel, Ulrich,Kinzel, Elke,Andrade, Juan,Prescher, Guenter

, p. 3326 - 3343 (2007/10/02)

A simple synthesis of (R,R)-3,4-bis(diphenylphosphino)pyrrolidine (6a) and some N-substituted derivatives 6b-m is described. 6l and 6m are optically active tetraphosphanes, composed of two (R,R)-3,4-bis(diphenylphosphino)pyrrolidine units and a dicarboxylic residue.The structure of the parent compound 6a was determined by X-ray diffraction.From the phosphanes 6a-m the cationic 1,5-cyclooctadiene-bisphosphane-rhodium complexes 7a-m were prepared.The complexes 7l and 7m are ligand bridged bis(rhodium) dications.The complexes 7a-m were used for the asymmetric catalytic hydrogenation of the α-(acylamino)acrylic acid derivatives 9a-l.Enantiomeric excesses up to 100percent were achieved.Between 1 and 70 at the optical yields do not depend on the hydrogen pressure.The substrate/catalyst ratio can be as high as 50000/1.
