Discussion Reaction of Mercaptans with Fluoro Oleflns.-The published method'for the synthesis of fluoroalkyl sulfides was found to be both inconvenient and hazardous2 and a better method has been developed. It has been found that the reaction proceeds readily even at temperatures below 0" and can be carried out by bubbling the fluoro olefin into the mercaptan in the presence of a basic catalyst. Sodium hydroxide, sodium methoxide, and ...
