Dehydromethylation of alkali metal salts of the utility amide 2,2,6,6-tetramethylpiperidide (TMP)

A general thermolysis reaction for the transformation of Group 1 TMP compounds (LiTMP, NaTMP, KTMP) to 1-aza-allylic TTHP derivatives is reported. TMEDA accelerates the reaction and produces the crystalline complexes [(TMEDA)LiTTHP] and [(TMEDA·NaTTHP)2]. Methane elimination during the transformational process was confirmed via TVA coupled to MS. This journal is the Partner Organisations 2014.

MECHANISMS OF FREE-RADICAL REACTIONS. XXV. REACTIVITY OF N-CHLORO-2,2,6,6-TETRAMETHYLPIPERIDINE IN FREE-RADICAL CHLORINATION OF ALIPHATIC COMPOUNDS

The chlorination of 2,3-dimethylbutane and cyclohexane by N-chloropiperidine and N-chloro-2,2,6,6-tetramethylpiperidine was studied.The rate of abstraction of the hydrogen atom from various positions is determined mainly by the dissociation energies of the respective C-H bonds.The higher reactivity of the R2CH2 group compared with R3CH for the last reagent is due to the significant sensitivity of the radical to steric factors.In the absence of highly reactive substrates N-chloro-2,2,6,6-tetramethylpiperidine dissociates through β-fragmentation of the radical-cation.
