can any one have idea for the synthesis of 2-chloropyridine-N-oxide.

i reacted TBC (terbutylcatecol) with NaOH and obtained a phenoxide
salt. the phenoxide salt was then reacted with sulphuric acid in order
to obtain TBC back. what i got was 2 phase separated layers. one was
orange in color and the other was clear liquid. i did an FTIR analysis

Could anyone suggest a good synthetic procedure for water free PhONa
and PhSNa?
Commercial samples do contain water.
Thanks!

Hello, all!
Could anyone help me to find an answer to the following question: what

is a mechanism of this reaction?

Hello. I'm looking for Carboxylic acids purification technics.
It sounds a little stupid, but isn't easy to find right procedures. I
work with beta lactamics derivatives, and I have to obtain very very
very very pure compound to work with the enzyme.
