The chemical compound "(C5(CH3)5)Rh(P(CH3)3)(C6(2)H4H)(2)H" is a rhodium-based organometallic complex. It features a rhodium (Rh) atom at its center, which is bonded to a pentamethylcyclopentadienyl (C5(CH3)5) ligand, a triethylphosphine (P(CH3)3) ligand, and two protonated (H) cyclohexadienyl (C6(2)H4H) ligands. This complex is characterized by its unique electronic properties and potential applications in homogeneous catalysis, particularly in the activation of small molecules and the formation of carbon-carbon bonds. The structure of the complex is stabilized by the coordination of these ligands to the rhodium center, which can influence its reactivity and selectivity in various chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 88704-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,7,0 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88704-35:
(7*8)+(6*8)+(5*7)+(4*0)+(3*4)+(2*3)+(1*5)=162
162 % 10 = 2
So 88704-35-2 is a valid CAS Registry Number.

Isotope Effects in Arene C-H Bond Activation by

Jones, William D.,Feher, Frank J.

, p. 4814 - 4819 (2007/10/02)

The isotope effects involved in the activation of arene C-H bonds by the intermediate have been investigated.The ratio kH/kD for coordination to a double bond in benzene (the rate-determining step of arene activation) is found to be 1.05(6), whereas kH/kD=1.4 for the second step in which the C-H bond of the coordinated arene undergoes oxidative addition.The isotope effect KH/D for the equilibrium between the more stable phenyl hydride complex (C5Me5)Rh(PMe3)(C6D5)H and the complex containing hydrogen in the ortho position of the phenyl ring (C5Me5)Rh(PMe3)(o-C6D4H)D shows a preference for hydrogen (vs. deuterium) on the metal of 2.7.The kinetic isotope effect for reductive elimination and dissociation of m-xylene from (C5Me5)Rh(PMe3)(3,5-C6H3Me2)H vs. (C5Me5)Rh(PMe3)(3,5-C6H3Me2)D is found to be inverse, with kH/kD=o.51.Analysis of the data for the deuterated benzene derivatives confirms that the kinetic isotope for the reductive elimination step is inverse.Attemps to prepare the complex (C5Me5)Rh(PMe3)(CH3)D by reduction of + with - resulted in the formation of both (C5Me5)Rh(PMe3)(CH3)D and (C5Me5)Rh(PMe3)(CH2D)H.
