Substituted phenyl esters of alpha-fluoroacrylic acid |
abstract |
Certain esters of alpha -fluoroacrylic acid are available via hydrolysis of alpha -hydroxymethyl- alpha -fluoromalonic esters, followed by decarboxylation of the hydrolysis product. Phenyl alpha -fluoroacrylates which are substituted on the phenyl radical can be prepared by hydroxymethylation of dimethyl alpha -fluoromalonates, decarboxylation and dehydration of the resultant dimethyl alpha -hydroxymethyl- alpha -fluoromalonate and esterification of the resultant alpha -fluoroacrylic acid with substituted phenols. The substituted phenyl alpha -fluoroacrylates are colourless liquids or colourless solids which are polymerisable. They are suitable as starting material for the preparation of fluorinated polymers. |
