1739-10-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1739-10-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1739-10:
(6*1)+(5*7)+(4*3)+(3*9)+(2*1)+(1*0)=82
82 % 10 = 2
So 1739-10-2 is a valid CAS Registry Number.

Ureate Titanium Catalysts for Hydroaminoalkylation: Using Ligand Design to Increase Reactivity and Utility

Man?en, Manfred,Deng, Danfeng,Zheng, Cameron H. M.,Dipucchio, Rebecca C.,Chen, Dafa,Schafer, Laurel L.

, p. 4550 - 4560 (2021/05/04)

Hydroaminoalkylation describes the atom-economical catalytic synthesis of amines by forming new Csp3-Csp3 bonds using readily available amine and alkene feedstocks. Herein, we describe an earth-abundant and cost-efficient titanium catalyst generated in si

Linear Hydroaminoalkylation Products from Alkyl-Substituted Alkenes

Warsitz, Michael,Doye, Sven

, p. 15121 - 15125 (2020/10/23)

The regioselective conversion of alkyl-substituted alkenes into linear hydroaminoalkylation products represents a strongly desirable synthetic transformation. In particular, such conversions of N-methylamine derivatives are of great scientific interest, because they would give direct access to important amines with unbranched alkyl chains. Herein, we present a new one-pot procedure that includes an initial alkene hydroaminoalkylation with an α-silylated amine substrate and a subsequent protodesilylation reaction that delivers linear hydroaminoalkylation products with high selectivity from simple alkyl-substituted alkenes. For that purpose, new titanium catalysts have been developed, which are able to activate the α-C?H bond of more challenging α-silylated amine substrates. In addition, a direct relationship between the ligand structure of the new catalysts and the obtained regioselectivity is described.

Dehydroxylation of alcohols for nucleophilic substitution

Chen, Jia,Lin, Jin-Hong,Xiao, Ji-Chang

, p. 7034 - 7037 (2018/07/05)

The Ph3P/ICH2CH2I system-promoted dehydroxylative substitution of alcohols was achieved to construct C-O, C-N, C-S and C-X (X = Cl, Br, and I) bonds. Compared with the previous approaches such as the Appel reaction and Mitsunobu reaction, this protocol offers some practical advantages such as safe operation and a convenient amination process.
