Benzene, 1-[(3-bromo-2-propynyl)oxy]-2,4-dichloro- is a complex organic chemical compound with the molecular formula C9H5BrCl2O. It is a derivative of benzene, featuring a bromine atom attached to a propargyl group, which is a three-carbon chain with a triple bond between the first and second carbon atoms. The compound also has two chlorine atoms attached to the benzene ring at the 2nd and 4th positions, and an oxygen atom connected to the propargyl group, forming an ether linkage. This molecule is characterized by its unique structure and reactivity, which can be utilized in various chemical reactions and applications, such as the synthesis of pharmaceuticals and other organic compounds. Due to its halogenated nature, it may also exhibit certain physical and chemical properties, such as increased solubility in organic solvents and potential reactivity with nucleophiles.

774-77-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 774-77-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 774-77:
(5*7)+(4*7)+(3*4)+(2*7)+(1*7)=96
96 % 10 = 6
So 774-77-6 is a valid CAS Registry Number.

THERMAL BEHAVIOUR OF ARYL γ-HALOPROPARGYL ETHERS

Ariamala, G.,Balasubramanian, K. K.

, p. 309 - 318 (2007/10/02)

A systematic study of the behaviour of aryl γ-halopropargyl ethers under thermal condition was undertaken.Aryl γ-bromopropargyl ethers 2 underwent unique transformation in N,N-diethylaniline (215 deg C, 6 h) giving rise to a mixture of products 3,4 and 5,whereas, under similar conditions aryl γ-chloropropargyl ethers 8, afforded 4-chlorochromenes, 9.A remarkable substituent and solvent effect has been observed in the thermolysis of these aryl γ-bromo and γ-chloropropargyl ethers, rendering this transformation as a method for the synthesis of a number of substituted 4-bromochromenes 3, 4-chlorochromenes 9 and chroman-4-ones 7.In contrast, solution thermolysis of aryl γ-iodopropargyl ether 11 afforded aryl propargyl ether 1 as the major product.
