Lithium acetylide N,N,N',N'-tetramethylethylenediamine complex is a chemical compound with the formula LiC≡C?TMEDA. It is a colorless, hygroscopic solid that is highly sensitive to air and moisture. This complex is formed by the reaction of lithium acetylide (LiC≡C) with N,N,N',N'-tetramethylethylenediamine (TMEDA), a bidentate amine ligand. The compound is widely used as a strong base and a nucleophile in various organic synthesis reactions, particularly in the formation of carbon-carbon bonds. Due to its reactivity, it is essential to handle lithium acetylenide N,N,N'N'-tetramethylethylenediamine complex under an inert atmosphere, such as nitrogen or argon, to prevent unwanted side reactions.

7437-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7437-45-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 7437-45:
(6*7)+(5*4)+(4*3)+(3*7)+(2*4)+(1*5)=108
108 % 10 = 8
So 7437-45-8 is a valid CAS Registry Number.
