摘要：
A 2-fluoroisobutyric acid ester can be obtained at a high yield in one pot by reacting a 2-hydroxyisobutyric acid ester with fluorosulfuric acid in the absence or presence of a hydrogen fluoride source, or by reacting a 2-hydroxyisobutyric acid ester with chlorosulfuric acid in the presence of a hydrogen fluoride source.
