Cyclononene, also known as 1,3,5,7-cyclononatetraene, is a cyclic hydrocarbon compound consisting of nine carbon atoms arranged in a non-aromatic, non-alternating double bond structure. It is an isomer of the more well-known non-benzenoid aromatic compound, cyclodecapentaene. Cyclononene is a highly reactive molecule due to its strained ring structure and the presence of multiple double bonds, making it an interesting subject for chemical research and potential applications in materials science. However, its instability and tendency to undergo rapid reactions limit its practical uses, and it is primarily studied for its theoretical and academic significance in understanding the properties of cyclic hydrocarbons.

3618-11-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3618-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,1 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3618-11:
(6*3)+(5*6)+(4*1)+(3*8)+(2*1)+(1*1)=79
79 % 10 = 9
So 3618-11-9 is a valid CAS Registry Number.

Synthesis of trans -Cycloalkenes via Enantioselective Cyclopropanation and Skeletal Rearrangement

Miura, Tomoya,Nakamuro, Takayuki,Liang, Chia-Jung,Murakami, Masahiro

, p. 15905 - 15908 (2015/02/19)

An efficient one-pot two-step procedure for asymmetric synthesis of piperidine-fused trans-cycloalkenes is reported. The method comprises the initial enantioselective installation of another cyclopropane ring onto methylenecyclopropanes and the subsequent thermal skeletal rearrangement in which the installed and inherent cyclopropane rings are both opened. A concerted mechanism is proposed for the latter thermal rearrangement reaction together with a closed transition state model.

Hydroindation of allenes and its application to radical cyclization

Hayashi, Naoki,Hirokawa, Yusuke,Shibata, Ikuya,Yasuda, Makoto,Baba, Akio

supporting information; experimental part, p. 1949 - 1954 (2009/01/31)

Hydroindation of allenes and radical cyclization of 1,2,7-trienes (allenenes) were accomplished by HInCl2 with high regioselectivity to afford a variety of cyclic compounds. The resulting vinylic indiums could be used for successive coupling reactions in a one-pot procedure. The use of HInCl2 generated slowly in situ is extremely effective for the radical cyclization.
