4303-71-3

Triphenylmethyl sodium, also known as sodium triphenylmethanide, is a highly reactive and powerful base with the chemical formula (C6H5)3CNa. It is a white crystalline solid that is soluble in organic solvents such as ether and benzene. TRIPHENYLMETHYL SODIUM is formed by the reaction of triphenylmethane with sodium metal, resulting in the displacement of hydrogen and the formation of a carbanion. Triphenylmethyl sodium is widely used in organic synthesis, particularly in the preparation of various organic compounds through nucleophilic substitution reactions. Due to its high reactivity, it is essential to handle this compound with extreme caution, as it can react violently with water and other protic solvents, leading to hazardous situations.

4303-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4303-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,0 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4303-71:
(6*4)+(5*3)+(4*0)+(3*3)+(2*7)+(1*1)=63
63 % 10 = 3
So 4303-71-3 is a valid CAS Registry Number.

Preparation and Characterization of Some Pentaarylethyls

Smith, William B.,Harris, Michael C.

, p. 4957 - 4962 (2007/10/02)

The reaction of triphenylmethylsodium with dichlorodiphenylmethane does not give pentaphenylethyl as previously reported, but when the anion reacts with 9,9-dichlorofluorene, it does form the reported 9-tritylfluorenyl radical which has been characterized by ESR spectroscopy.The radical is better prepared by oxidation of the anion of 9-tritylfluorene.The 9-tritylfluorenyl radical reacts with traces of oxygen to give triphenylmethyl and fluorenone.With light it forms triphenylmethyl and fluorenylidene.The latter was established by photolyzing 9-diazofluorene in the presence of triphenylmethyl with the generation of 9-tritylfluorenyl.Small yields of the persistent pentakis(p-tert-butylphenyl)ethyl radical have been prepared, and it is propable that pentaphenylethyl has also.

The steady illumination of triphenylsilyl anion and p-terphenyl (p-TP) in tetrahydrofuran yielded the radical anion of p-terphenyl (p-TP.-), which persisted after cutting of the light.When the triphenylmethylanion was used, p-TP.- wa
