25982-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25982-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,8 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25982-72:
(7*2)+(6*5)+(5*9)+(4*8)+(3*2)+(2*7)+(1*2)=143
143 % 10 = 3
So 25982-72-3 is a valid CAS Registry Number.

Selective Aerobic Oxygenation of Tertiary Allylic Alcohols with Molecular Oxygen

Zhu, Bencong,Shen, Tao,Huang, Xiaoqiang,Zhu, Yuchao,Song, Song,Jiao, Ning

, p. 11028 - 11032 (2019/07/08)

Aerobic epoxidation of tertiary allylic alcohols remains a significant challenge. Reported here is an efficient and highly chemoselective copper-catalyzed epoxidation and semipinacol rearrangement reaction of tertiary allylic alcohols with molecular oxygen. The solvent 1,4-dioxane activates dioxygen, thereby precluding the addition of a sacrificial reductant.

N-BuLi/LiCH2CN-mediated one-carbon homologation of aryl epoxides into conjugated allyl alcohols

Tomioka, Takashi,Sankranti, Rambabu,Yamada, Tsuyoshi,Clark, Courtney

supporting information, p. 5099 - 5101 (2013/10/22)

A series of styrene oxides in the presence of a 1:1 mixture of n-butyllithium (n-BuLi) and lithioacetonitrile (LiCH2CN) in THF are converted into one-carbon homologated allyl alcohols in an unusual regioselective manner.

A novel palladium-catalyzed asymmetric cyclocarbonylation of allylic alcohols to γ-butyrolactones

Yu, Wing-Yiu,Bensimon, Corinne,Alper, Howard

, p. 417 - 423 (2007/10/03)

A catalyst system based on [Pd2(dba)3]·CHCl3/(-)-BPPM has been found to effect asymmetric cyclocarbonylation of certain prochiral allylic alcohols to produce good yields of optically enriched γ-butyrolactones. The reaction
