17486-86-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17486-86-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,8 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17486-86:
(7*1)+(6*7)+(5*4)+(4*8)+(3*6)+(2*8)+(1*6)=141
141 % 10 = 1
So 17486-86-1 is a valid CAS Registry Number.

Titanocene(II)-promoted carbonyl cyclopropylidenation utilizing 1,1-dichlorocyclopropanes

Shono, Tomohiro,Nagasawa, Takehiro,Tsubouchi, Akira,Takeda, Takeshi

, p. 3521 - 3524 (2007)

A variety of alkylidenecyclopropanes bearing various substituents on their cyclopropane ring were obtained by the titanocene(II)-promoted reaction of 1,1-dichlorocyclopropane derivatives with carbonyl compounds including esters and lactones.

Hydrogenation of Ketones and Esters Catalyzed by Pd/C?SiO2

Akchurin,Baibulatov,Dokichev

, p. 195 - 198 (2018/03/26)

Hydrogenation of unsaturated ketones and esters with molecular hydrogen on the 5%Pd/C?SiO2 heterogeneous catalyst has been studied. The reaction direction and yield are determined by the starting compounds structure. Hydrogenation of unsaturated ketones containing phenyl group at the double carbon–carbon atom is accompanied by the reduction of the ketone group into the alcohol one. Hydrogenation of unsaturated esters is accompanied by transesterification.

Manganese-Catalyzed β-Alkylation of Secondary Alcohols with Primary Alcohols under Phosphine-Free Conditions

Liu, Tingting,Wang, Liandi,Wu, Kaikai,Yu, Zhengkun

, p. 7201 - 7207 (2018/07/21)

Manganese(I) complexes bearing a pyridyl-supported pyrazolyl-imidazolyl ligand efficiently catalyzed the direct β-alkylation of secondary alcohols with primary alcohols under phosphine-free conditions. The β-alkylated secondary alcohols were obtained in moderate to good yields with water formed as the byproduct through a borrowing hydrogen pathway. β-Alkylation of cholesterols was also effectively achieved. The present protocol provides a concise atom-economical method for C-C bond formation from primary and secondary alcohols.
