What is Methyl cyanoformate?
Description
Methyl cyanoformate is the organic compound with the formula CH3OC(O)CN. It is used as a reagent in organic synthesis as a source of the methoxy carbonyl group , in which context it is also known as Mander's reagent. It was also the active ingredient in the pesticide product Zyklon A.
Chemical properties
Colorless liquid; ethereal odor. Decomposedby alkalies and water. Soluble in alcohol, benzene,ether.
The Uses of Methyl cyanoformate
Organic synthesis.
The Uses of Methyl cyanoformate
Selective acylating reagent.
Purification Methods
Purify the ester by fractionation through a 45cm glass helices packed column or a 30cm spinning band column. [Sheppard J Org Chem 27 3756 1962.] It has been distilled through a short Vigreux column (p 11), and further purified by recrystallisation from Et2O at -40o as white crystals which melt at room temperature. NMR: 4.0 ( C3), and IR: 2250 (CN) and 1750 (CO) cm-1 . [Childes & Weber JOrg Chem 41 3486 1976, Beilstein 2 III 1587.]
