125655-26-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125655-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,5 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125655-26:
(8*1)+(7*2)+(6*5)+(5*6)+(4*5)+(3*5)+(2*2)+(1*6)=127
127 % 10 = 7
So 125655-26-7 is a valid CAS Registry Number.

The preparation and coordination chemistry of phosphorus(III) derivatives of dialkyl ureas and thioureas

Slawin,Wainwright,Woollins

, p. 2724 - 2730 (2007/10/03)

The preparation of Ph2PNEtC(O)NEtPPh2 and Ph2PNMeC(S)NMePPh2 is reported. The coordination chemistry of Ph2PNEtC(O)NEtPPh2, Ph2PNMeC(O)NMePPh2 and Ph2PNMeC(S)NMePPh2 with Pt(II) and Pd(II) has been studied. The urea derivatives react with MCl2(cod) (M = Pd, Pt) to give simple MCl2L complexes. Demonstrative examples of simple chelate Mo(CO)4L and bimetallic ClAu-L-AuCl complexes have also been prepared. However with Pd(OAc)2 bimetallic compounds [PdOPh2{N(Me)C(O)N(Me)PPh2}]2 containing hydrolysed ligands (P-N bond cleaved) are formed. Furthermore the thiourea compound reacts with PtCl2(cod) to give [Pt{Ph2PN(Me)- C(N(Me)HS)}Cl2], a true heterocycle containing a PtSCNP ring. The new compounds have been characterised spectroscopically and the X-ray structures of six complexes are reported.

Phosphino-urea chemistry: Preparation and structure of chelate and P-N bond cleavage complexes

Slawin, Alexandra M.Z.,Wainwright, Matthew,Woollins, J. Derek

, p. 69 - 71 (2007/10/03)

Reactions of Ph2PNRC(E)NRPPh2 proceed to give simple P,P chelate complexes when E = O but give the unexpected five-membered true heterocycle Pt[Ph2PN(Me)C(NMeH)S] Cl2 and an unusual six-membered Pd2P

Preparation of P-Chloro-Substituted N,N'-Dimethylurea-Bridged Diphosphorus Compounds, their Dehalogenation with Oxalic Acid Bis(trimethylsilyl) Ester and Subsequent Oxidation with Tetrachloro-o-benzoquinone

Vogt, Roland,Schmutzler, Reinhard

, p. 690 - 698 (2007/10/02)

Reaction of N,N'-dimethyl-N,N'-bis(trimethylsilyl)urea (1) with dichlorophosphines, RPCl2 (R = Et: 14; R = Pri: 15) has furnished the P-chloro-substituted acyclic diphosphorus compounds, 16 and 17.In the analogous reaction of 1 with Ph2PCl the corresponding bis(diphenylphosphino)-substituted derivative, 21 was formed.Dehalogenation of 11, 16 and 17 with oxalic acid bis(trimethylsilyl)ester, 22 has produced the mixed-valent cyclic λ3P, λ4P-diphosphorus compounds, 23-25 in almost quantitative yield.Oxidation of the λ3P atom in 23-25 with tetrachloroorthobenzoquinone, 26 has given rise to partial cleavage of the P-P bond, and only moderate yields of the products, 29, 31 and 32, have been obtained.The characterization of the various compounds obtained rests, especially, on their 1H and 31P NMR spectra, and on a study of their mass spectral fragmentation pattern. - keywords: N,N'-Dimethyl-N,N'-bis(trimethylsilyl)urea, N,N'-Dimethyl-N,N'-bisalkyl(chlorophosphino)urea, N,N'-Dimethyl-N,N'-bis(diphenylphosphino)urea, Oxalic Acid Bis(trimethylsilyl) Ester, Mixed Valence Diphosphorus Compounds
