Amines prim., hindered

A soln. of Na-dichlorisocyanurate in water added to a soln. of 4-benzoyl-2,2,6,6-tetramethylpiperidine in benzene, and vigorously shaken for several min product. Y 86%. Reaction is also applicable to non-hindered prim, or sec. amines, but the obtained chloramines are less stable. F.e.s. J. Zakrzewski, Synth. Commun. 18, 2135-40 (1988). 

Hindered sec. from prim, amines and 0x0 compds. via azomethines... 

Silver carbonate-on-Gelite has been recommended for the oxidation of alcohols to aldehydes and ketones. It does not attack hindered hydroxyl groups Prim, amines can be converted to ketones under mild conditions through prototropic isomerization of certain Schiff bases A variety of aldehydes, including deu-terio-, a, -ethylene-, and cycloalkane-aldehydes have been obtained in a novel manner from dihydro-1,3-oxazines Non-con-...
