(Re(CO)4(CON(Ph)C(Me)NPh)) is a complex organometallic compound consisting of a rhenium (Re) center coordinated with four carbonyl (CO) ligands and a bidentate Schiff base ligand, formed by the condensation of phenylhydrazine (PhNHNH2) with acetone (Me2CO). The Schiff base ligand, N-phenyl-N'-(1-phenylethylidene)-1,2-diaminoethane, features a phenyl group attached to the nitrogen atom and a phenylethylidene group connected to the other nitrogen atom. (Re(CO)4(CON(Ph)C(Me)NPh)) is of interest in the field of homogeneous catalysis, particularly in the study of olefin metathesis reactions, due to its potential as a catalyst precursor. The structure and electronic properties of the complex can be tuned by varying the substituents on the phenyl groups, which can influence its catalytic activity and selectivity.

Check Digit Verification of cas no

The CAS Registry Mumber 90523-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90523-09:
(7*9)+(6*0)+(5*5)+(4*2)+(3*3)+(2*0)+(1*9)=114
114 % 10 = 4
So 90523-09-4 is a valid CAS Registry Number.

RHENIUM CARBONYL COMPLEXES. SYNTHESIS AND CHARACTERISATION OF NN'-DIARYLAMIDINES, R'NHC(R)NR' (R=H, Me, or Ph, R'=Ph or C6H4Me-p), AND RELATED CARBAMOYL DERIVATIVES

NN'-Diarylacetamidines R'NHC(Me)NR', NN'-diarylbenzamidines R'NHC(Ph)NR', and NN'-diarylformamidines R'NHC(H)NR' (R'=Ph or C6H4Me-p) react thermally or photolytically with and/or 2> (X= Cl or Br) to afford air-stable, white complexes, X>, containing monodentate amidine ligands.The corresponding lithioamidines (R= Me or Ph) gave white carbamoyl complexes >, which are converted thermally to NN'-bidentate > and ortho-metallated > (R''=H or Me).The latter complexes are also formed by further reaction of the carbamoyl complexes with the corresponding amidine.The carbamoyl complexes react with PPh3 to form >.Lithioamidines in excess react with (X= Cl or Br) complexes to give adducts formulated as Li(1+)2>(1-).The new complexes are characterised, and structural data obtained by i.r. and n.m.r. spectroscopy.
