2,2-dibromo-1-methylcyclopropanecarbonyl chloride is a chemical compound with the molecular formula C5H6Br2ClO. It is a halogenated cyclopropane derivative, featuring a cyclopropane ring with a methyl group at the 1-position, and two bromine atoms at the 2-position. The molecule also contains a carbonyl chloride group, which is attached to the cyclopropane ring. 2,2-dibromo-1-methylcyclopropanecarbonyl chloride is known for its reactivity and can be used in the synthesis of various organic compounds, particularly those requiring a cyclopropane ring structure. Due to its halogenated nature, it may also have applications in the preparation of pharmaceuticals and agrochemicals. However, it is important to handle 2,2-dibromo-1-methylcyclopropanecarbonyl chloride with care, as it is likely to be toxic and hazardous due to its reactivity and the presence of multiple halogens.

Safety precautions

Handle with caution and appropriate safety measures due to potential hazards

Check Digit Verification of cas no

The CAS Registry Mumber 5365-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,6 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5365-22:
(6*5)+(5*3)+(4*6)+(3*5)+(2*2)+(1*2)=90
90 % 10 = 0
So 5365-22-0 is a valid CAS Registry Number.

Novel method for the synthesis of α- and β-halogenonaphthalenes by regioselective benzannulation of aryl(gem-dihalogenocyclopropyl)methanols: Application to the total synthesis of the lignan lactones, justicidin E and taiwanin C

Acid treatment of two types of aryl(gem-dihalogenocyclopropyl)methanols (ADCMs) 1 and 3 gives α- and β-halogenonaphthalenes in good yields with excellent selectivity. These alternative annulations involve two distinctive types of highly regioselective acid-induced cyclopropane ring cleavage, wherein the preferential formation of more stable cationic intermediates determines the selectivity. The stereochemical mode of both the preparation and the annulation between diastereoisomers of an ADCM has been checked. As a demonstration of this annulation, a total synthesis of each of the natural lignan lactones, justicidin E 19 and taiwanin C 20, has also been performed. Since these 4-arylnaphthalenes are expected to exhibit biological activity, the anti-platelet activating factor (anti-PAF) activity of justicidin E has been assayed.
