Abstract
We reported a straightforward, three step synthesis of 3,3‐difluorocyclobutane carboxylic acid.
Notes
1The material safety data sheet lists the following hazards: highly flammable, very toxic (EU definition), may cause cancer, causes burns, severe irritant.
2This paper reports the same transformation may be achieved using sulfur tetrafluoride, but the yield was not reported.
3After 2 days at room temperature an approximately 70:30 mixture of 1 and 10 was formed.
