Cyclopropanecarboxylic acid, 2,2-dichloro-, methyl ester is a chemical compound with the molecular formula C5H6Cl2O2. It is an organic ester derived from cyclopropanecarboxylic acid, where two chlorine atoms are attached to the cyclopropane ring, and a methyl group is esterified to the carboxylic acid group. Cyclopropanecarboxylic acid, 2,2-dichloro-, methyl ester is characterized by its unique cyclic structure and halogenated substituents, which can influence its reactivity and physical properties. It is typically synthesized for use in organic chemistry research and as an intermediate in the production of various pharmaceuticals and agrochemicals. Due to its specific structure, it may exhibit different chemical behaviors compared to other esters, making it a valuable compound for studying the effects of halogenation and ring strain on molecular properties.

3591-47-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3591-47-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,9 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3591-47:
(6*3)+(5*5)+(4*9)+(3*1)+(2*4)+(1*7)=97
97 % 10 = 7
So 3591-47-7 is a valid CAS Registry Number.

Catalyst Effects on Reactions of α,β-Unsaturated Ketones and Esters with Haloforms under Phase-Transfer Catalysis

Dehmlow, Eckehard V.,Wilkenloh, Juergen

, p. 582 - 588 (2007/10/02)

Reactions of acceptor-substituted alkenes with haloform/sodium hydroxide and PT-catalyst result in dihalocarbene additions competitive to Michael additions, with or without consecutive cyclization, and further reactions.Product compositions are strongly dependent on the nature of the phase-transfer catalyst: Sterically unhindered quarternary ammonium ions and benzo-crown ethers favour processes via carbenes, large delocalized (soft) cations foster primary Michael additions.Thus, tert-butyl cis-crotonate is dichlorocyclopropanated stereospecifically with NMe4Cl.The respective stereospecific CBr2 conversion is successful only with PhHgCBr3 .
