η3-1,2,3,4-tetraphenyl-5-ketocyclopentenylcyclopentadienylnickel is a complex organic compound that features a nickel atom at its core. η3-1,2,3,4-tetraphenyl-5-ketocyclopentenylcyclopentadienylnickel is characterized by a cyclopentadienyl ring, which is a five-membered ring with alternating double bonds, and a cyclopentenyl ring, which is a five-membered ring with one double bond. The cyclopentenyl ring in η3-1,2,3,4-tetraphenyl-5-ketocyclopentenylcyclopentadienylnickel is further modified by the presence of a keto group (C=O) at the 5-position, indicating the presence of a carbonyl group. The tetraphenyl substitution refers to the presence of four phenyl groups (C6H5-) attached to the cyclopentadienyl ring, which significantly influences the compound's steric and electronic properties. This complex structure endows the compound with unique chemical and physical characteristics, making it a subject of interest in organometallic chemistry and potentially in applications where such specific structural features are required.

Check Digit Verification of cas no

The CAS Registry Mumber 89389-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,8 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89389-58:
(7*8)+(6*9)+(5*3)+(4*8)+(3*9)+(2*5)+(1*8)=202
202 % 10 = 2
So 89389-58-2 is a valid CAS Registry Number.

REDUCTIVE SUBSTITUTION OF NICKELOCENE; INTERCEPTION OF A MONOHYDRIDO INTERMEDIATE IN THE HYDROGENATION OF 2,3,4,5-TETRAPHENYLCYCLOPENTADIENONE (TETRACYCLONE)

Slocum, D. W.,Moronski, Marek,Gooding, Richard,Duraj, Stan

, p. C26 - C28 (1984)

Reductive substitution of nickelocene with tetracyclone affords bis(tetracyclone)nickel(0) (1), η3-1,2,3,4-tetraphenyl-5-ketocyclopentenylcyclopentadienylnickel (2) and trans-1,2,3,4-tetraphenylcyclopenten-1-one-5 (3); evidence is presented that 2 is an intermediate in the formation of 3 from 1.
