Morpholin-4-ium morpholine-4-carbodithioate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2011
The title compound, C(4)H(10)NO(+)·C(5)H(8)NOS(2) (-), is built up of a morpholinium cation and a dithio-carbamate anion. In the crystal, two structurally independent formula units are linked via N-H⋯S hydrogen bonds, forming an inversion dimer, with graph-set motif R(4) (4)(12).

Highly efficient morpholine-based organocatalysts for the 1,4-addition reaction between aldehydes and nitroolefins: an unexploited class of catalysts

open access: yesFrontiers in Chemistry, 2023
Many studies have demonstrated how the pyrrolidine nucleus is more efficient than the corresponding piperidine or morpholine as organocatalysts in the condensation of aldehydes with electrophiles via enamine.
