74039-78-4 Usage
General Description
The chemical compound "Bis(tris(p-chlorophenyl)phosphine)mercuric chloride complex" is a complex formed by the combination of mercury and a phosphine ligand. The phosphine ligand contains three p-chlorophenyl groups, and it forms coordinate bonds with the mercury atom to create a stable complex. Bis(tris(p-chlorophenyl)phosphine)mercuric chloride complex has been studied for its potential use as a catalyst in various chemical reactions, and for its potential application in organic synthesis. It is important to handle this compound with care, as both mercury and chlorophenyl groups can be toxic and harmful to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 74039-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,3 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74039-78:
(7*7)+(6*4)+(5*0)+(4*3)+(3*9)+(2*7)+(1*8)=134
134 % 10 = 4
So 74039-78-4 is a valid CAS Registry Number.

A 31P and 199Hg nuclear magnetic resonance and vibrational spectroscopic study of triarylphosphine complexes of HgCl2
Allman, Tim,Goel, Ram G.
, p. 615 - 620 (2007/10/02)
Complexes of the type 2 and HgCl2(P(4-XC6H4)3)2 (x = Me2N, MeO, Me, H, F, Cl) have been prepared.The tertiary phosphines have similar steric requirements but vary gratly in their basicities.The vibrational spectra of the complexes were measuredand each complex was found to have the expected bridging dimeric (1:1) or pseudotetrahedral monomeric (1:2 Hg/P) structure.Their 31P and 199Hg nmr parameters were investigated and is was found that J(Hg-P) increases with increasing phosphine basicity, decreasing temperature, and decreasing sample concentration in dichloromethane solution.It is concluded that changes in the hybridisation on the P and Hg atoms may be largely responsible for increases of J(Hg-P) with increasing phosphine basicity.
