173542-96-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 173542-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,4 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173542-96:
(8*1)+(7*7)+(6*3)+(5*5)+(4*4)+(3*2)+(2*9)+(1*6)=146
146 % 10 = 6
So 173542-96-6 is a valid CAS Registry Number.

Preparation of cyclomanganated chalcones and their reactions with methyl acrylate and other α, β-unsaturated carbonyl compounds

Tully, Warren,Main, Lyndsay,Nicholson, Brian K.

, p. 75 - 92 (2007/10/03)

Chalcones react with benzyltetracarbonylmanganese under reflux in petroleum spirit to give two types of cyclomanganation products.The first, involving metallation at the alkenyl β-carbon of the enone, are derivatives of ethenyl-κC1>tetracarbonylmanganese, while the second type, manganated at the aryl ring ortho-carbon, are derivatives of phenyl-κC1>tetracarbonylmanganese.In general, more "alkene-manganed" than "ring-manganated" product is formed, with the ratio influenced significantly by certain substituents, e.g. a 4-CF3 substituent on the phenyl ring at C3 of the enone strongly promotes "alkene-manganation".In some cases there are minor by-products derived from coupling of two chalcone molecules after initial cyclomanganation.The crystal structures are reported for two such products, *, 2R*, 3S*)-1-hydroxy-1-((E)-2-(2-trifluoromethylphenyl)ethenyl)-3-(2-trifluoromethylphenyl)-6-methoxy-2-indanylcarbonyl-κO)-6-methoxyphenyl-κC1>tetracarbonylmanganese and (1S*, 4S*, 5R*)-5-(4-bromobenzoyl)-1-(4-bromophenyl)-3-4-di-(4-trifluoromethylphenyl)cyclopent-2-en-1-ol.In acetonitrile under reflux, alkene-manganated chalcones react with methyl acrylate (methyl propenoate) to form derivatives of methyl (E)-4,6-diphenyl-6-oxohex-2-enoate and of 5-(2-methoxycarbonylethyl)-3,5-diphenylfuran-2(5H)-one.The latter butenolides are not formed when the reactions are carried out in carbon tetrachloride, only the former α,β-unsaturated esters.By contrast, in a few reactions studied, acrolein (propenal) and methyl vinyl ketone (but-3-en-2-one) give only the butenolide products when treated with alkene-manganated chalcones in refluxing acetonitrile.An exception is the reaction of methyl vinyl ketone with ethenyl-κC1>tetracarbonylmanganese to form the cyclized product 5-acetyl-1-(4-chlorophenyl)-3-(3,4,5-trimethoxyphenyl)cyclopent-2-en-1-ol.Keywords: Manganese; Alkene; Chalcones; Crystal structure; Cyclometallation; Metallacycle
