C(sp2)–H Functionalizations Employing 2-Aminophenyl-1H-pyrazole as a New Removable Directing Group
… source, 1,1,3,3-tetramethylguanidine (TMG) as an organic base, the reaction, optimally carried out overnight in DMSO at 80 °C in open air, produced a variety of products in moderate to excellent yields. In addition, C(sp2)–H bond chlorination has been developed by using this auxiliary, employing …

The use of immobilised crown ethers as in-situ protecting groups for organic synthesis within flow reactors
Organic synthesis often requires one functional group of a bifunctionalised compound to be rendered temporarily inert to allow the selective reaction of another moiety. While protecting groups are used to remove the problem of the functional group incompatibility, they also raise other issues such …

Novel Switchable Stationary Phase Methods For Supercritical Fluid Chromatography
… phase was investigated for the analysis of organic bases. The method uses a stainless steel capillary column coated with water containing NH4OH, which was also used to hydrate the system. In this way, the pH of the water stationary phase can be effectively altered to help control the …

Oxidation of Transition Metal Complexes with 3,7-Diazabicyclo[3.3.1]nonane-Derived Ligands
… by tuning the reaction conditions (applying an organic base or a basic alumina in the synthesis), the distance between the copper(II) centers could be varied. Vanadyl-complexes with N2py2 and N2py2PhOH were also prepared and their spectroscopic properties compared to the known …
