Triphenyl<2-(2-ethyliden)cyclopentylmethyl>phosphoniumbromid is a complex organic compound with the chemical formula C46H44BrP2. It is a phosphonium salt, characterized by the presence of a phosphonium cation and a bromide anion. The molecule features a central phosphorus atom bonded to three phenyl groups and a cyclopentylmethyl group, which in turn is connected to another phosphorus atom through an ethylidene bridge. This secondary phosphorus atom is also bonded to two phenyl groups, forming a triphenylphosphoranyliden group. The compound is of interest in organic chemistry, particularly in the study of phosphorus-containing compounds and their applications in various chemical reactions and processes.

Check Digit Verification of cas no

The CAS Registry Mumber 79058-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,0,5 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79058-77:
(7*7)+(6*9)+(5*0)+(4*5)+(3*8)+(2*7)+(1*7)=168
168 % 10 = 8
So 79058-77-8 is a valid CAS Registry Number.

Open-chain and Cyclic Bis-phosphoranes from α,ω-Dinitriles, Diisobutylaluminium Hydride, and Methylenetriphenylphosphorane

Bogdanovic, Borislav,Hullen, Albert,Konstantinovic, Stanimir,Krawiecka, Bozena,Mynott, Richard

, p. 2261 - 2271 (2007/10/02)

The reaction of subero-, azelao-, and sebaconitrile (4, n = 6, 7, and 8) with diisobutylaluminium hydride (to give 5) and subsequenly with methylenetriphenylphosphorane leads to the openc-hain bis-phosphoranes 8 a-c, which have been characterized by the Wittig reaction.The same reaction sequence applied to adiponitrile produces the cyclic bis-phosphorane 9a.The previously unknown hydrocarbon 1,3,9,11-cyclohexadecatetraene (12) has been prepared from 8a and adipoaldehyde.
