68012-05-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68012-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 68012-05:
(7*6)+(6*8)+(5*0)+(4*1)+(3*2)+(2*0)+(1*5)=105
105 % 10 = 5
So 68012-05-5 is a valid CAS Registry Number.

Synthesis and structure of group 4 symmetric amidinate complexes and their reactivity in the polymerization of α-olefins

Elkin, Tatyana,Kulkarni, Naveen V.,Tumanskii, Boris,Botoshansky, Mark,Shimon, Linda J. W.,Eisen, Moris S.

, p. 6337 - 6352 (2013/12/04)

The steric properties of various nitrogen substituents on amidines were tuned in order to obtain group 4 mono- and bis(amidinate) dimethylamido or chloride complexes. The amidinate dimethylamido and chloride complexes were prepared, and their solid-state

Deep eutectic solvent promoted highly efficient synthesis of N, N'-diarylamidines and formamides

Azizi, Najmadin,Gholibeglo, Elham,Babapour, Mahbobe,Ghafuri, Hossein,Bolourtchian, Seyed Mohammad

, p. 768 - 773 (2012/10/30)

A deep eutectic solvent was used as a dual catalyst and reaction medium for the efficient N-formylation of aromatic amines without hazardous organic solvent and catalyst. Treatment of aromatic amines with trimethyl orthoformate and formic acid in deep eutectic solvent at 70 °C gives the corresponding N-formyl derivatives in good to excellent yields. This simple ammonium deep eutectic solvent, easily synthesized from choline chloride and SnCl2, with 100% atom economy and making it applicable to industry and laboratory. Furthermore, heating the trimethyl orthoformate and aromatic primary amines in the deep eutectic solvent results in formation of the corresponding N,N'-diarylamidines in high yields.

Expanded ring and functionalised expanded ring N-heterocyclic carbenes as ligands in catalysis

Binobaid, Abeer,Iglesias, Manuel,Beetstra, Dirk J.,Kariuki, Benson,Dervisi, Athanasia,Fallis, Ian A.,Cavell, Kingsley J.

experimental part, p. 7099 - 7112 (2010/02/15)

The synthesis of new functionalised 6- and 7-membered NHC (N-heterocyclic carbene) precursors bearing anisidyl or pyridine N-substituents, both symmetrically and non-symmetrically substituted is reported. Their corresponding rhodium(i) and iridium(i) complexes, M(COD)(NHC)Cl, were also prepared and characterised. The unusual Rh(iii)/Rh(i) salt, [Rh(η2-NHC-py) 2Cl2][Rh(COD)Cl2], was obtained with one of the pyridyl-functionalised NHC ligands. Single-crystal X-ray analyses have been obtained for the majority of the complexes and NHC salts. The activity of these complexes was tested in the hydrogenation of a range of substrates with molecular hydrogen, including 1-cyclooctadiene and 2-methyl styrene, where they show enhanced activity and stability in comparison to non-functionalised NHC analogues, operating under exceptionally mild conditions (ambient temperature and atmospheric pressure).
