880-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 880-22-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 880-22:
(5*8)+(4*8)+(3*0)+(2*2)+(1*2)=78
78 % 10 = 8
So 880-22-8 is a valid CAS Registry Number.

Paragraph 0030-0032; 0044, (2018/06/26)

PROBLEM TO BE SOLVED: To provide a production method of an allyl compound of carrying out the dehydration allylation of a substrate having S, C or N which is a nucleophilic atom, especially S under the presence of a catalyst system consisting of a catalyst precursor having a specific structure and a specific ligand. SOLUTION: The production method of allyl compounds comprises as follow. A catalyst precursor chosen from Formula (1) and Formula (2) and a ligand are mixed, or a catalyst precursor, an allyl alcohol, and a ligand are mixed, then allyl alcohols and a substrate are blended and made to react. The ligand is quinaldic acid or picolinic acid, and the substrate is thiols, thiocarboxylic acids or the like. [Ru(C5H5)(CH3CN)3]PF6(1). [Ru[C5(CH3)5](CH3CN)3]PF6(2). COPYRIGHT: (C)2012,JPOandINPIT

Catalytic activation of diazo compounds using electron-rich, defined iron complexes for carbene-transfer reactions

Holzwarth, Michael S.,Alt, Isabel,Plietker, Bernd

supporting information; experimental part, p. 5351 - 5354 (2012/07/14)

Carbene transfer: The electron-rich iron complex Bu4N[Fe(CO) 3(NO)] efficiently catalyzes different carbene-transfer reactions. Various diazo compounds can be used. The high stability of the employed iron complexes is demonstrated by the generation of the diazo reagent in situ and a sequential iron-catalyzed allylic sulfenylation/Doyle-Kirmse reaction.

Palladium-catalyzed insertion reactions of trimethylsilyldiazomethane

Greenman, Kevin L,Carter, David S,Van Vranken, David L

, p. 5219 - 5225 (2007/10/03)

Palladium(II) salts catalyze the Kirmse reaction of allylsulfides with trimethylsilyldiazomethane (TMSD) to give homoallylsulfides. Similarly, TMSD can intercept ArPdX intermediates generated during Stille couplings to give benzhydryl derivatives. The yie
