General Description
[(S)-2,2'-BIS(DIPHENYLPHOSPHINO)-1,1'-BINAPHTHYL]BIS(2-METHYLALLYL)RUTHENIUM(II) is a complex chemical compound that contains ruthenium as its central metal atom. It is widely used as a catalyst in various organic transformations, including hydrogenation, isomerization, and olefin metathesis reactions. The presence of the chiral ligand, specifically the 1,1'-binaphthyl backbone, imparts stereochemical control to the catalyst, making it highly useful in asymmetric synthesis. Additionally, the two 2-methylallyl groups and the diphenylphosphino ligands also contribute to the reactivity and selectivity of the complex. Overall, this compound is an important tool in modern synthetic organic chemistry, enabling the efficient and selective formation of complex molecules with high stereochemical purity.
Check Digit Verification of cas no
The CAS Registry Mumber 133773-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133773-19:
(8*1)+(7*3)+(6*3)+(5*7)+(4*7)+(3*3)+(2*1)+(1*9)=130
130 % 10 = 0
So 133773-19-0 is a valid CAS Registry Number.

The co-crystallization of Ru((R)-binap)(η3-Me-allyl)2 and binap dioxide, and synthesis of Ru(Ph2P(CH2)4PPh2)(η 3-Me-allyl)2

The molecular structure of the 2-methylallyl species Ru((R)-binap)(η3-Me-allyl)2 (3) was established by X-ray crystallography of a crystal of 3a, the asymmetric unit of which is composed of half of a molecule of 3 and half of a (R)-(+)-2,2′-bis(diphenylphosphinoyl)-1,1′-binaphthyl(binap dioxide) molecule, co-crystallized with two disordered deuterobenzenes; crystals of 3a are tetragonal, space group I422, with Z=8, a=21.344(1) A and c=36.453(2) A. The structure was solved by direct methods and refined by full-matrix least-squares procedures to R=0.034 and Rw=0.032 for 3431 reflections with I≥3σ(I). The 1,4-bis(diphenylphosphino)butane (dppb) analogue (2) of 3 was also prepared and characterized by 1H and 31P{1H}-NMR spectroscopy and elemental analysis, and the reactivities of 2 and 3 toward halogen acids are discussed.
