A lab scale procedure
When its used paraformaldehyde is possible the formation of the six membered ring, but I am wondering how to overcome Schiff base formation when normal R-CHO aldehydes are the reagents. Thanks for your contribution.
Please aid with software as well as strategies in order to get X-ray structure in a similar fashion to single crystal X-ray refinement. We have D2 Phaser-Bruker XRD instrument to obtain PXRD data...
