144266-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144266-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,6 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144266-44:
(8*1)+(7*4)+(6*4)+(5*2)+(4*6)+(3*6)+(2*4)+(1*4)=124
124 % 10 = 4
So 144266-44-4 is a valid CAS Registry Number.

Study of O-allylation using triazine-based reagents

Yamada, Kohei,Hayakawa, Naoko,Fujita, Hikaru,Kitamura, Masanori,Kunishima, Munetaka

, p. 112 - 115 (2017)

Acid-catalyzed allylating reagent 2,4,6-tris(allyloxy)-1,3,5-triazine (TriAT-allyl) and its substituted derivatives have been developed. The reaction of acid-, and alkali-labile alcohols with these reagents in the presence of a catalytic amount of trifluoromethanesulfonic acid (TfOH) afforded the corresponding allyl ethers in good yields. Reactions using these reagents with an unsymmetrically-substituted regioisometric allyl group suggested that a single isometric allylic cation species would be involved.

Nickel Hydride Catalyzed Cleavage of Allyl Ethers Induced by Isomerization

Kathe, Prasad M.,Berkefeld, Andreas,Fleischer, Ivana

supporting information, p. 1629 - 1632 (2021/02/09)

This report discloses the deallylation of O - and N -allyl functional groups by using a combination of a Ni-H precatalyst and excess Bronsted acid. Key steps are the isomerization of the O - or N -allyl group through Ni-catalyzed double-bond migration followed by Bronsted acid induced O/N-C bond hydrolysis. A variety of functional groups are tolerated in this protocol, highlighting its synthetic value.

Isomerization of allyl ethers initiated by lithium diisopropylamide

Su, Chicheung,Williard, Paul G.

supporting information; experimental part, p. 5378 - 5381 (2011/02/27)

Lithium diisopropylamide (LDA) promotes virtually quantitative conversion of allylic ethers to (Z)-propenyl ethers. It was discovered that allylic ethers can be isomerized efficiently with very high stereoselectivity to (Z)-propenyl ethers by LDA in THF a
