Bis(triphenylphosphoranyliden)hydrazin, also known as diphenylphosphinohydrazone, is a chemical compound with the formula (Ph3P=N-N=PPh3). It is a white crystalline solid that is soluble in organic solvents. Bis(triphenylphosphoranyliden)hydrazin is a bidentate ligand, meaning it can form two separate coordination bonds with a metal center. It is widely used in coordination chemistry, particularly in the formation of transition metal complexes, due to its ability to stabilize certain geometries and electronic configurations. Bis(triphenylphosphoranyliden)hydrazin is also known for its potential applications in catalysis and as a precursor in the synthesis of other phosphorus-containing compounds.

752-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 752-23-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 752-23:
(5*7)+(4*5)+(3*2)+(2*2)+(1*3)=68
68 % 10 = 8
So 752-23-8 is a valid CAS Registry Number.

Dinitrogen as double lewis acid: Structure and bonding of triphenylphosphinazine N2(PPh3)2

Holzmann, Nicole,Dange, Deepak,Jones, Cameron,Frenking, Gernot

, p. 3004 - 3008 (2013)

Making Ns meet: Triphenylphosphinazine N2(PPh3) 2 is a donor-acceptor complex between nitrogen in the highly excited 1Γg state and two anti-periplanar coordinated phosphine ligands (see structure). Although the dissociation into N 2+2 PPh3 is calculated to be exergonic by 75 kcal mol -1, the compound is kinetically very stable as a result of the very large Lewis acidity of N2 in the excited 1Γ g state.
