2-Oxetanone, 4-(chloromethyl)-, also known as 4-(chloromethyl)-2-oxetanone or 4-chloromethyl-2-oxetanone, is a chemical compound with the molecular formula C4H5ClO2. It is a cyclic ketone with a four-carbon ring structure, featuring a chloromethyl group (-CH2Cl) attached to the fourth carbon atom and a carbonyl group (C=O) at the second carbon atom. 2-Oxetanone, 4-(chloromethyl)- is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactivity, it is essential to handle 4-(chloromethyl)-2-oxetanone with caution, as it can undergo nucleophilic addition reactions and participate in other chemical transformations.

6737-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6737-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6737-16:
(6*6)+(5*7)+(4*3)+(3*7)+(2*1)+(1*6)=112
112 % 10 = 2
So 6737-16-2 is a valid CAS Registry Number.

Low pressure carbonylation of heterocycles

-

Page/Page column 4, (2008/06/13)

Heterocycles, e.g., epoxides, are carbonylated at low pressure with high percentage conversion to cyclic, ring expanded products using the catalyst where L is tetrahydrofuran (THF).

Practical β-lactone synthesis: Epoxide carbonylation at 1 atm

Kramer, John W.,Lobkovsky, Emil B.,Coates, Geoffrey W.

, p. 3709 - 3712 (2007/10/03)

A readily prepared bimetallic catalyst is capable of effecting epoxide carbonylation to produce β-lactones at substantially lower CO pressures than previously reported catalyst systems. A functionally diverse array of β-lactones is produced in excellent yields at CO pressures as low as 1 atm. This procedure allows for epoxide carbonylation on a multigram scale without the requirement of specialized, high-pressure equipment.
