Tri-p-tolyl-2-acetyl-3,4,5-triphenylcyclopentadienylide is a complex organic compound characterized by its unique molecular structure. It features a cyclopentadienyl core, which is a five-membered ring with alternating double bonds, and is adorned with three phenyl groups at positions 3, 4, and 5. Each of these phenyl groups has a p-tolyl substituent, which is a methyl group attached to the para position of the benzene ring. Additionally, the compound has an acetyl group (a two-carbon fragment derived from acetic acid) attached to the 2-position of the cyclopentadienyl ring. This molecule is significant in organic chemistry due to its potential applications in the synthesis of various complex molecules and its structural properties that can influence its reactivity and stability.

Check Digit Verification of cas no

The CAS Registry Mumber 86281-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 86281-84:
(7*8)+(6*6)+(5*2)+(4*8)+(3*1)+(2*8)+(1*4)=157
157 % 10 = 7
So 86281-84-7 is a valid CAS Registry Number.

TRITOLYLARSONIUM AND TRIS(METHOXYPHENYL)ARSONIUM YLIDES THE EFFECTS OF ortho-SUBSTITUENTS IN TRIARYLARSONIUM GROUPS ON THE PROPERTIES OF YLIDES

Harris, Gordon S.,Lloyd, Douglas,MacDonald, William A.,Gosney, Ian

, p. 297 - 304 (2007/10/02)

A number of tritolylarsonium and tris(methoxyphenyl)arsonium cyclopentadienylides and other ylides have been prepared and their properties (basicity, NMR spectra, reactions with aldehydes and nitrosobenzene, acetylation, and methanolysis) have been investigated.Substituents in the m- or p-positions of triarylarsonium groups have little effect on properties, but o-substituents result in markedly lower reactivity and lower basicity, and these ylides were also more difficult to prepare.NMR spectra gave indication of crowding in some of these o-substituted ylides.The effects of the o-substituents are discussed. p-Methyl- and p-methoxy-substituents increased the proportion of anil to ketoxime formed in reactions with nitrosobenzene, but the o-methoxy analogue gave only ketoxime.
