Hello, I did one reaction but the product appears to be very insoluble in organic solvents.
I did one sample to send to NMR, the quality of the signal is very poor and I coulnd't even make a ¹³C spectrum because the poor quality
The problem is, I would see duplets, but I only see thin singlets, is it possible that the quality is so poor that I can't see the real multiplicty? I did one COSY and I saw correlations between these singlets, so I think is very strange one singlet be coupled with other singlet with J3.
What do you guys think?
