A Crystalline Ylide‐Stabilized Stibenium Cation
The isolation of a stibenium cation stabilized by two thiophosphinoyl‐tethered ylide groups is reported. The cation is accessible via salt metathesis of the metalated ylide with SbCl3 and features CSb single bonds, with lone pairs remaining localized at the ylidic carbon atoms.

2.8 Recent Advances in N-Heterocyclic Carbene Organocatalysis
In recent years, organocatalysis has seen a rapid rise in popularity and this has led to a subsequent increase in the research output of the area, with organocatalysis by N-heterocyclic carbenes (NHCs) playing a significant role.

Enantioselective homogeneous catalysts for the synthesis of fluorinated organic compounds
This thesis is divided into three main results chapters that reflect the path my research took. In the first results chapter, the first organocatalyst for the carbonyl-ene reaction was discovered and found to give high conversion using 1,3-bis(3,5-bis ...

Asymmetric synthesis of tetrahydroquinolines through supramolecular organocatalysis
Functionalized chiral tetrahydroquinolines were synthesized through supramolecular organocatalysis using quinidine-NH-thiourea 3c/L-phenylalanine 4i followed by reductive amination from the simple ...

Herein, an organocatalytic asymmetric synthesis of dihydroquinoline/hydantoin hybrids is described. The synthetic protocol involves a tandem reaction comprising a phosphoric acid–catalyzed initial Povarov dimerization of in situ generated imine/enamine mixtures under tautomeric equilibrium, followed by a Urech–Read reaction of the 1,2‐dihydroquinoline ...
