Check Digit Verification of cas no

The CAS Registry Mumber 800394-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,0,3,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 800394-58:
(8*8)+(7*0)+(6*0)+(5*3)+(4*9)+(3*4)+(2*5)+(1*8)=145
145 % 10 = 5
So 800394-58-5 is a valid CAS Registry Number.

Efficient synthesis of tris-heteroleptic iridium (III) complexes based on the Zn2+-promoted degradation of tris-cyclometalated Iridium (III) complexes and their photophysical properties

We report on the efficient synthesis of tris-heteroleptic iridium (Ir) complexes based on the degradation of triscyclometalated Ir complexes (IrL3, L: Cyclometalating ligand) in the presence of Br?nsted and Lewis acids such as HCl (in 1,4- dioxane), AlCl3, TMSCl, and ZnX2 (X = Br or Cl), which affords the corresponding halogen-bridged Ir dimers (μ-complexes). Tris-cyclometalated Ir complexes containing electron-withdrawing groups such as fluorine, nitro, or CF3 moieties on the ligands were less reactive. This different reactivity was applied to the selective degradation of heteroleptic Ir complexes such as fac- Ir(tpy)2(F2ppy) (fac-12) (tpy: 2-(4'-tolyl)pyridine and F2ppy: 2-(4',6'-difluorophenyl)pyridine), mer-Ir(tpy) 2 (F2ppy) (mer-12), and mer-Ir(mpiq)2(F2ppy) (mer-15) (mpiq: 1-(4'-methylphenyl)isoquinoline). For example, the reaction of mer-12 with ZnBr2 gave the heteroleptic μ-complex [{Ir(tpy)(F2ppy)(μ-Br)}2] 27b as a major product, resulting from the selective elimination of the tpy ligand of mer-12, and treatment of 27b with acetylacetone (acacH) afforded the corresponding tris-heteroleptic Ir complex Ir(tpy)(F2ppy)(acac)18. In addition, another tris-heteroleptic Ir complex 35a having 8-benzenesulfonylamidoquinoline (8BSQ) ligand was synthesized. Mechanistic studies of this degradation reaction and the photochemical properties, especially a dual emission, of these newly synthesized tris-heteroleptic Ir complexes are also reported.

Probing the mer- to fac-isomerization of tris-cyclometallated homo- and heteroleptic (C,N)3 iridium(III) complexes

We have developed techniques which allow for covalent tethering, via a hetero cyclometallating ligand, of heteroleptic tris-cyclometallated iridium(III) complexes to polymeric supports (for application in light-emitting diode technologies). This involved the selective synthesis and thorough characterization of heteroleptic [Ir(C,N)2(C′,N′)] tris-cyclometallated iridium(III) complexes. Furthermore, the synthesis and characterization of heteroleptic [Ir(C,N)2OR] complexes is presented. Under standard thermal conditions for the synthesis of the facial (fac) isomer of tris-cyclometallated complexes, it was not possible to synthesize pure heteroleptic complexes of the form [Ir(C,N)2(C′,N′)]. Instead, a mixture of homo- and heteroleptic complexes was acquired. It was found that a stepwise procedure involving the synthesis of a pure meridonial (mer) isomer followed by photochemical isomerization of this mer to the fac isomer was necessary to synthesize pure fac-[Ir(C,N)2(C′, N′)] complexes. Under thermal isomerization conditions, the conversion of mer-[Ir(C,N)2(C′,N′)] to fac-[Ir(C,N) 2(C′,N′)] was also not a clean reaction, with again a mixture of homo- and heteroleptic complexes acquired. An investigation into the thermal mer to fac isomerization of both homo- and heteroleptic tris-cyclometallated complexes is presented. It was found that the process is an alcohol-catalyzed reaction with the formation of an iridium alkoxide [Ir(C,N)2OR] intermediate in the isomerization process. This catalyzed reaction can be carried out between 50 and 100°C, the first such example of low-temperature mer-fac thermal isomerization. We have synthesized analogous complexes and have shown that they do indeed react so as to give fac-tris-cyclometallated products. A detailed explanation of the intermediates (and all of their stereoisomers, in particular when systems of the generic formula [M(a,b)2(a′,b′')] are synthesized) formed in the mer to fac isomerization process is presented, including how the formed intermediates react further, and the stereoisomeric products they yield.
