Propylidenecyclopentane, also known as 1-methyl-1-cyclopenten-3-ylpropane, is a cyclic hydrocarbon compound with the molecular formula C8H14. It consists of a cyclopentane ring with a propylidene group (a three-carbon chain with a double bond between the first and second carbon atoms) attached to one of the carbon atoms in the ring. This organic compound is a colorless liquid with a pungent odor and is insoluble in water. It is used as an intermediate in the synthesis of various chemicals, including pharmaceuticals and fragrances, and is also found in trace amounts in petroleum. Due to its reactive nature, propylidenecyclopentane can undergo various chemical reactions, such as addition, substitution, and rearrangement, making it a versatile building block in organic chemistry.

5623-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5623-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5623-78:
(6*5)+(5*6)+(4*2)+(3*3)+(2*7)+(1*8)=99
99 % 10 = 9
So 5623-78-9 is a valid CAS Registry Number.

An Agostic Iridium Pincer Complex as a Highly Efficient and Selective Catalyst for Monoisomerization of 1-Alkenes to trans-2-Alkenes

Wang, Yulei,Qin, Chuan,Jia, Xiangqing,Leng, Xuebing,Huang, Zheng

supporting information, p. 1614 - 1618 (2017/02/05)

A unique Ir complex (tBuNCCP)Ir with the pyridine–phosphine pincer as the sole ligand, featuring a dual agostic interaction between the Ir and two σ C?H bonds from a tBu substituent, has been prepared. This complex exhibits exceptionally high activity and excellent regio- and stereoselectivity for monoisomerization of 1-alkenes to trans-2-alkenes with wide functional-group tolerance. Reactions can be performed in neat reactant on a more than 100 gram scale using 0.005 mol % catalyst loadings with turnover numbers up to 19000.
