7334-51-2 Usage

General Description

N,N,N',N'-Tetramethylsuccinyldiamide, also known as TMSD, is a chemical compound commonly used as a reagent in synthetic organic chemistry. It is a white crystalline solid that is soluble in common organic solvents. TMSD is often used as a protecting group for amines, allowing for selective modification of other functional groups in organic molecules. It is also utilized in the preparation of amides and carboxylic acids, as well as in the synthesis of pharmaceuticals and agrochemicals. TMSD has low toxicity and is considered to be relatively safe to handle when used in accordance with proper laboratory procedures.

Check Digit Verification of cas no

The CAS Registry Mumber 7334-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7334-51:
(6*7)+(5*3)+(4*3)+(3*4)+(2*5)+(1*1)=92
92 % 10 = 2
So 7334-51-2 is a valid CAS Registry Number.

Neutral complexes of first row transition metals bearing unbound thiocyanates and their assembly on metallic surfaces

Ciszek, Jacob W.,Keane, Zachary K.,Cheng, Long,Stewart, Michael P.,Yu, Lam H.,Natelson, Douglas,Tour, James M.

, p. 3179 - 3189 (2006)

A series of transition metal coordination complexes designed to assemble on gold surfaces was synthesized, their electronic structure and transitions analyzed, and their magnetic properties studied. By taking advantage of recently developed thiocyanate assembly protocols, these molecules were then assembled onto a gold surface, without the need for an inert atmosphere, to give a loosely packed monolayer. The assembled molecules exhibit properties similar to that of the bulk molecules, indicating little change in molecular structure outside of chemisorption.

A fulvene route to group 4 metallocene complexes bearing 4,7-bis(dimethylamino)-substituted indenyl ligands

Sierra, Jesus Cano,Kehr, Sierra Gerald,Froehlich, Roland,Erker, Gerhard

, p. 2260 - 2265 (2004)

N,N,N′,N′-Tetramethylsuccinamide (15) was selectively converted into the functionalized aminofulvene 16. Subsequent treatment with reagent 17, [ZrCl2(NMe2)2(L)2] (L = THF or 0.5 DME), resulted in the formation of the cyclization product 4,7- bis(dimethylamino)indene (21). Deprotonation with n-butyllithium, followed by the reaction of the resulting substituted indenyllithium reagent 22 with ZrCl4, gave the metallocene [4,7-bis(dimethylamino)indenyl] 2ZrCl2 (23). The reaction of 22 with ZrCl3Cp furnished the complex [4,7-bis(dimethylamino)indenyl]CpZrCl2 (24). Fulvene 16, as well as the metallocene dichlorides 23 and 24, were characterized by X-ray diffraction. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.

Copper-catalyzed homodimerization of nitronates and enolates under an oxygen atmosphere

Do, Hien-Quang,Tran-Vu, Hung,Daugulis, Olafs

, p. 7816 - 7818 (2013/01/16)

A method for copper-catalyzed oxidative dimerization of nitronates and enolates using oxygen as the terminal oxidant has been developed. Cyclization through oxidative intramolecular coupling is also feasible for both nitronates and enolates. The mild reaction conditions lead to good functional group tolerance.

Synthesis and antitumor activity of 2,5-bis(3′-indolyl)-furans and 3,5-bis(3′-indolyl)-isoxazoles, nortopsentin analogues

Diana, Patrizia,Carbone, Anna,Barraja, Paola,Kelter, Gerhard,Fiebig, Heinz-Herbert,Cirrincione, Girolamo

experimental part, p. 4524 - 4529 (2010/08/22)

A series of novel 2,5-bis(3′-indolyl)furans and 3,5-bis(3′-indolyl)isoxazoles were synthesized as antitumor agents. The antiproliferative activity was evaluated in vitro toward diverse human tumor cell lines. Initially 5 isoxazoles and 3 furan derivatives were tested against a panel of 10 human tumor cell lines and the most active derivatives 3c and 4a were selected to be evaluated in an extended panel of 29 cell lines. By exhibiting mean IC50 values of 17.4 μg/mL (3a) and 20.5 μg/mL (4c), in particular 4c showed a high level of tumor selectivity toward the 29 cell lines.
