Ammonium piperidine-1-carbodithioate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The title compound, NH(4) (+)·C(6)H(10)NS(2) (-), is composed of an ammonium cation and a piperidine-1-carbodithio-ate anion which exhibits positional disorder. The atoms of the ring have a structural disorder and they are divided into two sites, with occupancy factors of 0.584 and 0.426..

Synthesis and kinetic resolution of N-Boc-2-arylpiperidines [PDF]
, 2014 The chiral base n-BuLi/(-)-sparteine or n-BuLi/(+)-sparteine surrogate promotes kinetic resolution of N-Boc-2-arylpiperidines by asymmetric deprotonation. The enantioenriched starting material was recovered with yields 39-48% and ers up to 97:3.

Structures of piperazine, piperidine and morpholine [PDF]
Acta Crystallographica Section B Structural Science, 2004 The crystal structures of piperazine, piperidine and morpholine have been determined at 150 K. All three structures are characterized by the formation of NH...N hydrogen-bonded chains. In piperazine these are linked to form sheets, but the chains are shifted so that the molecules interleave. In morpholine there are in addition weak CH...O interactions.

[Co(TPP)]‐Catalyzed Formation of Substituted Piperidines
Chemistry, 2019 Radical cyclization via cobalt(III)‐carbene radical intermediates is a powerful method for the synthesis of (hetero)cyclic structures. Building on the recently reported synthesis of five‐membered N‐heterocyclic pyrrolidines catalyzed by CoII porphyrins ...
