Cyclopropane, (2-methyl-1-propenyl)-, also known as 2-methyl-1-(1-cyclopropanyl)propene, is an organic compound with the molecular formula C6H10. It is a colorless liquid with a pungent odor and is derived from the cyclopropane ring structure, which consists of three carbon atoms bonded in a cyclic arrangement. Cyclopropane, (2-methyl-1-propenyl)- is characterized by its unique ring structure and the presence of a methyl group attached to the propenyl chain. It is used in various chemical reactions and as an intermediate in the synthesis of other organic compounds. Due to its reactive nature, it is important to handle Cyclopropane, (2-methyl-1-propenyl)- with care, as it can be flammable and may pose health risks if not properly managed.

1003-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1003-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1003-33:
(6*1)+(5*0)+(4*0)+(3*3)+(2*3)+(1*3)=24
24 % 10 = 4
So 1003-33-4 is a valid CAS Registry Number.

Mechanistic Aspects of Gas-Phase Photodecarbonylation Reactions of Bicyclohexanones

Mariano, Patrick S.,Bay, Elliott,Watson, Darrell G.,Rose, Timothy,Bracken, Christopher

, p. 1753 - 1762 (2007/10/02)

The gas-phase photodecarbonylation and photofragmentation reactions of substituted bicyclohexan-3-ones have been studied in detail.Photolysis of these ketones yields 1,3-dienes, vinylcyclopropanes, and 1,4-dienes as detectable products.The possible mechanisms for these reactions are discussed in light of the regiochemical and stereochemical results obtained.In addition, methyl substitution at C-6 and C-2 of these ketones has been shown to have a pronounced effect on both product ratios and overall reaction efficiency.These effects are discussed in terms of stereoelectronic and electronic controls of rates of cyclopropane ring opening of intermediate acylcyclopropylcarbinyl diradicals.
