Benzenamine, N-ethynyl-N-methyl-, also known as N-methyl-4-ethynyl-aniline or 4-ethynyl-N-methylaniline, is an organic compound with the chemical formula C9H9N. It is a derivative of aniline, where a methyl group is attached to the nitrogen atom and an ethynyl group is present at the para position of the benzene ring. This colorless to pale yellow liquid is soluble in organic solvents and has a molecular weight of 131.18 g/mol. It is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is important to handle Benzenamine, N-ethynyl-N-methyl- with care, following proper safety protocols.

4231-31-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4231-31-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4231-31:
(6*4)+(5*2)+(4*3)+(3*1)+(2*3)+(1*1)=56
56 % 10 = 6
So 4231-31-6 is a valid CAS Registry Number.

Triphenylbismuth Dichloride-Mediated Conversion of Thioamides to Nitriles

Gopi, Elumalai,Gravel, Edmond,Doris, Eric

, p. 4043 - 4045 (2019)

Thioamides were efficiently converted to nitriles using the pentavalent triphenylbismuth dichloride in combination with triethylamine. The reaction involved the dehydrosulfurization of primary thioamides to afford substituted aromatic or aliphatic nitriles in good to excellent yields. The process was also successfully extended to the synthesis of cyanamides starting from the corresponding thioureas and of thiocyanates from dithiocarbamates.
