400828-03-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 400828-03-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,8,2 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 400828-03:
(8*4)+(7*0)+(6*0)+(5*8)+(4*2)+(3*8)+(2*0)+(1*3)=107
107 % 10 = 7
So 400828-03-7 is a valid CAS Registry Number.

Dual platinum and pyrrolidine catalysis in the direct alkylation of allylic alcohols: Selective synthesis of monoallylation products

Shibuya, Ryozo,Lin, Lu,Nakahara, Yasuhito,Mashima, Kazushi,Ohshima, Takashi

supporting information, p. 4377 - 4381 (2014/05/06)

A dual platinum- and pyrrolidine-catalyzed direct allylic alkylation of allylic alcohols with various active methylene compounds to produce products with high monoallylation selectivity was developed. The use of pyrrolidine and acetic acid was essential, not only for preventing undesirable side reactions, but also for obtaining high monoallylation selectivity. Two cats are better than one: The combined use of platinum and pyrrolidine catalysts enabled the direct alkylation of allylic alcohols with reactive methylene compounds. Pyrrolidine was essential for obtaining high selectivity of the monoallylation products, which were produced without the use of excess nucleophiles. cod=1,5- cyclooctadiene, EWG=electron-withdrawing group.

(π-Allyl)palladium complexes bearing diphosphinidenecyclobutene ligands (DPCB): Highly active catalysts for direct conversion of allylic alcohols

Ozawa, Fumiyuki,Okamoto, Hideyuki,Kawagishi, Seiji,Yamamoto, Shogo,Minami, Tatsuya,Yoshifuji, Masaaki

, p. 10968 - 10969 (2007/10/03)

The (π-allyl)palladium complex bearing an sp2-hybridized phosphorus ligand (DPCB-OMe: 1,2-bis(4-methoxyphenyl)-3,4-bis[(2,4,6-tri-tert-butylphenyl)phosphinidene]cyclobutene) efficiently catalyzes direct conversion of allylic alcohols in the absence of activating agents of alcohols such as Lewis acids. N-Allylation of aniline proceeds at room temperature to afford monoallylated anilines in 90-97% yields. C-Allylation of active methylene compounds is also successful at 50 °C using a catalytic amount of pyridine as a base, giving monoallylation products in 85-95% yields. The catalytic mechanism involving hydrido- and (π-allyl)palladium intermediates has been proposed on the basis of stoichiometric examinations using model compounds of presumed intermediates.

Palladium(0)-Catalyzed Substitution of Allylic Substrates in an Aqueous-Organic Medium

Blart, Errol,Genet, Jean Pierre,Safi, Mohamed,Savignac, Monique,Sinou, Denis

, p. 505 - 514 (2007/10/02)

A palladium(0)-water soluble catalyst prepared in situ from palladium acetate and the sulfonated triphenyl phosphine P(C6H4-m-SO3Na)3 (or tppts) is an efficient catalyst for allylic substitution with various carbon and heteronucleophiles in an aqueous-organic medium, allowing a very easy separation of the product(s) and the recycling of the catalyst.
