Tri-m-tolyl-(2,3,4-triphenyl-cyclopenta-2,4-dienylidene)-λ5-arsane is a complex organoarsenic compound characterized by a unique structure. It features a cyclopentadienyl ring with two carbon atoms double-bonded (dienylidene) and three phenyl groups attached to it, which are in turn substituted with methyl groups on the meta positions. The central arsenic atom is bonded to three of the carbon atoms of the cyclopentadienyl ring, forming a λ5-arsane structure. Tri-m-tolyl-(2,3,4-triphenyl-cyclopenta-2,4-dienylidene)-λ5-arsane is of interest in organometallic chemistry due to its potential applications in catalysis and material science, as well as its intriguing electronic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 86268-30-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,6 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86268-30:
(7*8)+(6*6)+(5*2)+(4*6)+(3*8)+(2*3)+(1*0)=156
156 % 10 = 6
So 86268-30-6 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.
