manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon‐carbon single (C−C) and carbon‐carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C−C vs. C=C bonds can be controlled by the

Onium amides, generated in situ from the combination of aminosilanes and onium fluorides (R(4)PF, R(4)NF), are employed for the first time as bases for catalytic deprotonative functionalization of C(sp(2))-H and activatedC(sp(3))-H bonds under mild conditions.
One-Pot Enantioselective Aziridination of Olefins Catalyzed by a Copper(I) Complex of a Novel Diimine Ligand by Using PhI(OAc)2 and Sulfonamide as Nitrene Precursors

A novel chiral C(2)-symmetric 1,4-diamine with multistereogenic centers at the backbone of the ligand has been synthesized from cheap natural product D-mannitol through multistep transformations. Its diimine derivative (3 a) was found to be highly effective for the enantioselective control of the copper-catalyzed asymmetric aziridination of olefin derivatives with PhI==NTs as the nitrene source, affording
