The photosensitized monomerization of the cyclobutane dimers of 1,3-dimethylthymine by p-chloranil was investigated by means of steady-state irradiation and laser-flash photolysis. Quantum yields for the monomerization are 0.34 for the cis,syn dimer, 0.39 for the trans,syn dimer, and much less

Starting from D-(-)-ribose, a tricyclic natural product-like scaffold suitable for combinatorial derivatization was synthesized via an intramolecular hetero-Diels-Alder reaction. Lithium perchlorate was found to enhance the reaction rate and, at the same time, had a pronounced influence on the chemoselectivity

A series of pyridine- and lutidine-linked bis-N-heterocyclic carbene (NHC) palladium pincer complexes were electrochemically characterized and screened for CO2 reduction capability with 2,2,2-trifluoroethanol, acetic acid, or 2,2,2-trifluoroacetic acid (TFA) as proton sources. The lutidine-linked pincer complexes electrocatalytically reduce CO2 to
The first enantioselective synthesis of both Diels-Alder enantiomers with the same bis (oxazoline)-magnesium perchlorate chiral catalyst.

The interaction of Mg2+ cations in biological systems is studied by using nucleic acid bases as the biological system. Magnesium salts, such as, MgCl2 6H2O, MgSO4. 7H2O and Mg(ClO4). XH2O have been employed in order to compare their complexation with

We have investigated the photosensitized monomerization of the cis,syn-cyclobutane dimer of 1,3-dimethylthymine using riboflavin tetraacetate and a 5-deazaflavin derivative as photosensitizer. Although little monomerization of the dimer is induced by photoexcitation of the flavins in the absence of any additives

[reaction: see text] A new mild method for protecting alcohols as t-butyl ethers is reported. The reaction proceeds with Mg(ClO4)2 and Boc2O and shows general applicability. The deprotection of t-butyl ethers has also been revisited. Preliminary results indicate the CeCl3

We have used time-resolved multidimensional vibrational spectroscopy, generally termed 2DIR spectroscopy, to study the equilibrium dynamics of ligand exchange in an aqueous solution containing 3.4 M Mg(ClO(4))(2) and 1.2 M NaSCN. The sensitivity of the CN stretching frequency of thiocyanate

The mechanism of the gamma-radiolysis of the nucleotide guanosine-5'-monophosphate (5'-GMP) in the presence of Mg++ ions and cis-platinum was investigated. From high performance liquid chromatography and spectroscopy studies it was found that the OH radicals, produced in irradiated aqueous solutions

Commercially available magnesium perchlorate is reported as an extremely efficient catalyst for the synthesis of alpha-aminophosphonates. A three-component reaction (3-CR) of an amine, an aldehyde or a ketone, and a di-/trialkyl phosphite (Kabachnik-Fields reaction) took place in one pot under

This study examined the effects on the radiolysis of magnesium-guanosine-5'-monophosphate complexes in deaerated aqueous solutions, investigated by Fourier transform infrared (FT-IR) spectroscopy. It was found that when the system was irradiated with a dose rate of 500 rad/min (low dose

The measurement of the UV-vis absorption spectrum of α-tocopheroxyl (α-Toc(•)) radical was performed by reacting aroxyl (ArO(•)) radical with α-tocopherol (α-TocH) in acetonitrile solution including four kinds of alkali and alkaline earth metal salts (MX or MX(2)) (LiClO(4), LiI, NaClO(4)

Structure determination of reactive species is a key step in understanding reaction mechanisms. We demonstrate the application of polarization-dependent two-dimensional infrared spectroscopy (P2D-IR) as a powerful tool combining structure resolution with ultrafast time resolution. We apply this technique to investigate
