Diazene, (diphenylphosphinyl)phenyl- (9CI), also known as 1-(diphenylphosphino)-2-phenyldiazene, is an organic compound with the chemical formula C18H15N2P. It is a derivative of diazene, which is a diazenyl group (-N=N-) bonded to a phenyl group (C6H5) and a diphenylphosphino group (C6H5)2P. Diazene,(diphenylphosphinyl)phenyl- (9CI) is characterized by its yellowish color and is sensitive to air and moisture. It is primarily used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from light and heat. The compound's applications extend to various fields, including catalysis and the synthesis of pharmaceuticals, where its unique electronic properties can influence the reactivity and selectivity of the metal centers in the complexes.

2227-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2227-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2227-40:
(6*2)+(5*2)+(4*2)+(3*7)+(2*4)+(1*0)=59
59 % 10 = 9
So 2227-40-9 is a valid CAS Registry Number.

Novel method for preparing phosphoryl azo compound (by machine translation)

-

Paragraph 0007; 0013, (2020/12/15)

The method adopts pyridine as a base, takes an aryl diazonium tetrafluoroborate compound and P (O)- H as a reaction substrate, and an organic solvent is added to the reaction system. The method has the advantages that the catalyst is cheap and easy to obtain. The substrate applicability is high. The reaction condition is mild, safe and reliable. The selectivity of the obtained target product is close 100%, and the yield is high. The method solves the harsh reaction conditions of the traditional synthetic phosphoryl azo compound. The reaction selectivity is poor, the experiment steps are tedious, the yield is low and the harmful reagents and the like on the environment are required to be used, and the industrial application prospect is good. The invention also provides a corresponding phosphoryl azo compound containing different substituted functional groups. (by machine translation)
