6,7,8,9-tetrahydro-1,2,3,4-tetraphenyl-5H-benzocycloheptene is a complex organic compound with a unique molecular structure. It is a derivative of benzocycloheptene, which is a seven-membered ring containing one benzene ring fused to a cycloheptene ring. The compound is characterized by the presence of four phenyl groups attached to the carbon atoms at positions 1, 2, 3, and 4, and a tetrahydro (four hydrogen atoms) substitution at positions 6, 7, 8, and 9. This molecule is known for its rigid and planar structure, which can be attributed to the conjugation between the phenyl rings and the cycloheptene ring. Due to its specific structure, it has potential applications in various fields, such as materials science and medicinal chemistry, where its unique properties can be exploited for specific purposes.

Check Digit Verification of cas no

The CAS Registry Mumber 751-58-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 751-58:
(5*7)+(4*5)+(3*1)+(2*5)+(1*8)=76
76 % 10 = 6
So 751-58-6 is a valid CAS Registry Number.

Generation of cycloheptynes and cyclooctynes via a sulfoxide-magnesium exchange reaction of readily synthesized 2-sulfinylcycloalkenyl triflates

Yoshida, Suguru,Karaki, Fumika,Uchida, Keisuke,Hosoya, Takamitsu

, p. 8745 - 8748 (2015/05/20)

Cycloheptynes and cyclooctynes were efficiently generated via a sulfoxide-magnesium exchange reaction of readily synthesized 2-sulfinylcycloalkenyl triflates. Cycloadditions between various ynophiles and the cycloalkynes generated by this method proceeded

Bi-3H-diazirin-3-yls as precursors of highly strained cycloalkynes

Al-Omari, Mohammad,Banert, Klaus,Hagedorn, Manfred

, p. 309 - 311 (2007/10/03)

(Chemical Equation Presented) No reagents and very mild conditions are required for the transformation of isolable precursors 3 into highly strained cycloalkynes 4 (cycloheptyne, cyclohexyne, norbornyne), which can be trapped by cycloaddition reactions.

A spontaneous fragmentation: From the Criegee zwitterion to coarctate Mobius aromaticity

Berger, Christian,Bresler, Christian,Dilger, Ulrich,Geuenich, Daniel,Herges, Rainer,Roettele, Herbert,Schroeder, Gerhard

, p. 1850 - 1853 (2007/10/03)

The extremely fast fragmentation of the spiroozonides prepared from formaldehyde O-oxide and three-membered ring ketones proceeds via the coarctate transition state 1. The ozonides decompose at temperatures as low as -90°C to form carbon dioxide, alkene/alkyne, and formaldehyde (the topology of the structure of 1 is depicted on the right). The mechanism is in accordance with the rules for the stereochemical course of coarctate reactions.
