i want to syntheis of 2-(2,2-difluoroethoxy)-6-(trifluoromethyl)benzene-1-sulfonyl chloride from
2- chloro-6-trifluoromethylaniline though ethoxylation

experiment1 :

mixture of 2- chloro-6-trifluoromethylaniline 0.1mol KOH 0.2mol 2,2-difluoroethanol 0.11mol

reaction tem 60 degree

but i find that recation is not react

question :

which method about this reaction , pls tell me ?

I think the normal way to ask questions is for the requester to supply some references or idea of why they think the scheme they present should work. Another way to make the difluorothoxy might be to take the phenol and react it with difluoroethene under basic conditions. I have done that type of reaction with tetrafluoroethene to make tetrafluoroethoxyphenyl compounds, but do not know if the difluoroethene would work well or what mix of regiosomers that you would get.
