194861-23-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 194861-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,8,6 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 194861-23:
(8*1)+(7*9)+(6*4)+(5*8)+(4*6)+(3*1)+(2*2)+(1*3)=169
169 % 10 = 9
So 194861-23-9 is a valid CAS Registry Number.

Photoinduced Fragmentation Borylation of Cyclic Alcohols and Hemiacetals

Aggarwal, Varinder K.,Madhavachary, Rudrakshula,Noble, Adam,Shu, Chao

supporting information, p. 7213 - 7218 (2020/10/12)

A visible-light photoinduced fragmentation borylation of O-phthalimido cycloalkanols with bis(catecholato)diboron is described. Structurally diverse keto and formyloxy alkyl boronic esters are shown to be conveniently prepared by radical-mediated ring opening of cyclic alcohols and hemiacetals, respectively. The reactions proceed under mild conditions in the absence of additives or photocatalysts, display excellent functional group tolerance, and are shown to allow cleavage of 4-, 5-, 6-, and 7-membered ring substrates. The mechanism proceeds via sequential homolytic N-O and C-C bond cleavages, the latter of which involves β-scission of an alkoxy radical, generating a carbonyl and an alkyl radical that is trapped by the diboron reagent. Spectroscopic studies suggest direct photoexcitation of either the phthalimide or diboron substrates with blue light can initiate a radical chain mechanism.

Direct C-H Trifluoromethylation of Glycals by Photoredox Catalysis

Wang, Bang,Xiong, De-Cai,Ye, Xin-Shan

supporting information, p. 5698 - 5701 (2015/12/01)

A mild, efficient, and practical transformation for the direct C-H trifluoromethylation of glycals under visible light has been reported for the first time. This reaction employed fac-Ir3+(ppy)3 as the photocatalyst, Umemoto's reagent as the CF3 source, and a household blue LED or sunlight as the light source. Glycals bearing both electron-withdrawing and -donating protective groups performed this reaction smoothly. This visible light-mediated trifluoromethylation reaction was highlighted by the trifluoromethylation of the biologically important Neu2en moiety.
