To acquire further insight into the structure-activityrelationship (SAR) of the thiocarbamates (TCs) described in the preceding work, 57 analogues of the lead compound O-(2-phenylethyl)-N-phenylthiocarbamate I were prepared by parallel solution-phase synthesis. We varied the 2-phenylethyl moiety (mono-substitution on the phenyl ring and modification of the ethyl linker), keeping constant the N-phenyl

E‐alkenes were synthesized with up to 100 % E/Z selectivity via ruthenium‐catalyzed partial hydrogenation of different aliphatic and aromatic alkynes under transfer‐hydrogenation conditions. Paraformaldehyde as a safe, cheap and easily available solid hydrogen carrier was used for the first time as hydrogen source in the presence of water for transfer‐hydrogenation of alkynes. Optimization reactions showed

With an [Ir(COD)Cl]2/phosphoramidite ligand system, an allylic substitution of O-allyl carbamothioates was developed. The reaction proceeded in the favor of branched products with up to 93:7 branched-to-linear ratio, affording chiral S-allyl carbamothioates with up to 95% ee.
