Reagents for the Mitsunobu Reaction
One of the most powerful and widely used carboncarbon bond forming reactions in organic synthesis is the Mitsunobu reaction.
Stabilized 2-Iodoxybenzoic Acid (SIBX)
IBX is not often used due to the fact that it is an impact-sensitive explosive material, which prevents its shipping and transport, as well as its application in industry.

New Aromatic Terminal Alkynes
The terminal alkyne functionality has a wide range of applications including most recently the synthesis of spiropyran substituted 2,3-dicyanopyrazines and (±)-asteriscanolide, as well as conversion to enamines using resin-bound 2° amines.
Aldehydes
Aldehydes are perennially attractive building blocks due to their ability to easily react with many nucleophiles.
MeO-BIPHEP
With Ru-complexes of this atropisomeric diphosphine ligand, b-keto esters are reduced to their corresponding b-hydroxy esters in high enantioselectivities.
Crystallization
The elucidation of a macromolecular structure to the atomic level by X-ray or neutron diffraction analysis requires the molecule to be available in the form of relatively large single crystals. Many soluble proteins, membrane proteins, nucleic acids and nucleoprotein complexes

Imidazolium Derived Reagents
N-Acylimidazoles were recognized in the early 1950s as reactive intermediates suitable for the acylation of amino compounds. The search for better coupling reagents than DCC led to the development of CDI (1,1’-carbonyldiimidazole) and related carbonylimidazoles.
Second-Generation, Designer-Surfactant Kits: Aqueous Reactions in a Box
Reactions once dependent on organic solvents are now being performed in water to eliminate the contributions of organic solvents to chemical waste – and the methodology just became easier with next-generation designer surfactant kits.
