Trimethyl-(1,2,3-triphenyl-cycloprop-2-enyl)-silane is a complex organic compound with the molecular formula C27H25Si. It features a cyclopropane ring with a double bond at the 2-position, which is substituted by three phenyl groups. Attached to the silicon atom are three methyl groups. Trimethyl-(1,2,3-triphenyl-cycloprop-2-enyl)-silane is of interest in organic synthesis and organosilicon chemistry due to its unique structure and potential applications in the formation of new carbon-carbon bonds and as a ligand in transition metal-catalyzed reactions. It is a colorless solid that is sensitive to air and moisture, and thus requires careful handling under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 87189-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87189-99:
(7*8)+(6*7)+(5*1)+(4*8)+(3*9)+(2*9)+(1*9)=189
189 % 10 = 9
So 87189-99-9 is a valid CAS Registry Number.

Triphenylcyclopropenide Anion in the Gas Phase

Bartmess, John E.,Kester, John,Borden, Weston T.,Koeser, Hans Guenther

, p. 5931 - 5934 (2007/10/02)

The triphenylcyclopropenide anion has been generated in the gas phase, and the approximate gas phase acidity of triphenylcyclopropene is reported.The dimethylphenylcyclopropenide has been also formed, but it appears to undergo a rearrangement that is induced by the acids used to probe its base strength.
