62311-60-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62311-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,3,1 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 62311-60:
(7*6)+(6*2)+(5*3)+(4*1)+(3*1)+(2*6)+(1*0)=88
88 % 10 = 8
So 62311-60-8 is a valid CAS Registry Number.

Palladium(0)-Catalyzed Azidation of Allyl Esters. Selective Synthesis of Allyl Azides, Primary Allylamines, and Related Compounds

Murahashi, Shun-Ichi,Taniguchi, Yuki,Imada, Yasushi,Tanigawa, Yoshio

, p. 3292 - 3303 (2007/10/02)

Palladium(0)-catalyzed reaction of allyl esters such as phosphates, carbonates, and carboxylates with sodium azide gives allyl azides.The azidation proceeds with retention of configuration at the allylic carbon.Optically active (R)-(E)-(+)-4-phenyl-3-buten-2-yl azide (19) is obtained from (R)-(E)-(+)-4-phenyl-3-buten-2-yl acetate (18) stereoselectively.Sequential substitution of (Z)-4-acetoxy-2-buten-1-yl diethyl phosphate (24) with nucleophiles and subsequently azide ion gives (E)-4-substituted-2-buten-1-yl azides 27.The reaction of allyl azides with triphenylphosphine gives iminotriphenylphosphoranes, which are versatile synthetic intermediates of primary allylamines, N-allylamines, and N-allylamides.Treatment of allyl azides with triphenylphosphine and subsequently with aqueous ammonium solution gives primary allylamines.Other synthetic applications of allyl azides are also described.
