Diethyl 2-[(morpholin-4-yl)(phenyl)methyl]malonate
Acta Crystallographica Section E Structure Reports Online, 2007 In the title compound, C18H25NO5, the morpholine unit adopts an almost ideal chair conformation. The crystal structure is consolidated by C—H⋯O intermolecular hydrogen-bond interactions, providing stabilization. The molecular conformation shows two possible pockets ready to coordinate two metal atoms.

Synthesis of carbon-13-labeled tetradecanoic acids.
Journal of Lipid Research, 1983 The synthesis of tetradecanoic acid enriched with 13C at carbons 1, 3, or 6 is described. The label at the carbonyl carbon was introduced by treating 1-bromotridecane with K13CN (90% enriched) to form the 13C-labeled nitrile, which upon hydrolysis ...
