Scale-Up Guide: Photocatalysis Reaction
Scale-Up Guide for Photocatalysis Reaction to best enable scale-up success with High-Throughput Screening Kit.
Greener Methods: Catalytic Amide Bond Formation
We are proud to offer a number of products used in catalytic amidation technology.
Phosgene and Phosgene Substitutes
Phosgene is 170 times more reactive than TP, the main phosgene substitute. Therefore, reactions with phosgene can be carried out under much milder conditions than with TP. Compounds will react faster and at lower temperatures (often at -78°C), preserving sensitive...
Q-Phos
Developed by Professor John Hartwig, pentaphenyl(di-tert-butylphosphino)ferrocene (Q-Phos) has emerged to be a premier ligand in coupling reactions with its remarkably broad utility in a variety of C–N, C–O, and C–C bondforming reactions.
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...
Glycosyltransferases: Tools for Synthesis and Modification of Glycans
The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.

Task-Specific Ionic Liquids
Task-Specific Ionic Liquids (TSILs) for the selective liquid/liquid extraction of heavy metals from aqueous systems were first published by Robin D. Rogers et al. in the year 2001.
Leighton’s Strained Silacycles
Prof. James L. Leighton has developed constrained five-membered silacycles. These chiral silane Lewis acid reagents are useful chiral catalysts in enantioselective allylations of simple aldehydes or hydrazones for the preparation of chiral carbinols and carbinamines.
Benzoylation Reagents
The α-hydroxycarbonyl moiety is an important structural motif in organic synthesis and is present in a substantial number of natural products.

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.
Applications for Bis(pyridine)iodonium Tetrafluoroborate
Bis(pyridine)iodonium tetrafluoroborate is a mild iodinating and oxidizing reagent capable of selectively reacting with a wide range of unsaturated substrates and tolerates a variety of functional groups.
BASIONICS™, BASF’s Portfolio of Ionic Liquids
Under the trade name BASIONICS™, BASF offers a portfolio of Ionic Liquids—mainly based on imidazolium cations. The BASIONICS™ portfolio opens up a broad range of basic properties of Ionic Liquids and is classified into standard, acidic, basic, liquid at RT...
Evans-Type Auxiliaries
The asymmetric aldol reaction mediated by chiral auxiliaries is considered to be one of the most important methods for asymmetric C-C bond formation.
Tetrakis(dimethylamino)ethylene (TDAE)
In 2001, Professor William Dolbier, Jr., at the University of Florida reported1 an approach to nucleophilic trifluoromethylation based on the generation of a trifluoromethyl anion using CF3I in the presence of a powerful twoelectron reductant, tetrakis(dimethylamino)ethylene (TDAE)
Dietary Terpenes
Terpenes comprise the largest and most diverse class of secondary metabolites; approximately 55,000 compounds have been identified to date.
LAB Reagents
Lithium aminoborohydride (LAB) reagents are a new class of powerful and selective reagents developed in the laboratory of Professor Bakthan Singaram at the University of California, Santa Cruz.
