Synthesis and Chemiluminescent Investigation of Malonyl Peroxides
… 4-methyl-4-phenyl-1,2-dioxolane-3,5-dione (3), 4-diphenylmethyl-4-methyl-1,2-dioxolane-3,5-dione (4), and 4-methyl-4-(1-propenyl)-1,2-dioxolane-3,5-dione (5) are prepared by the methanesulfonic acid catalyzed reaction of hydrogen peroxide with the parent malonic acids. Weak chemiluminescence is …

Thioetherification and Etherification Utilizing Trichloroacetimidates Under Thermal Conditions & Progress Towards an Efficient Synthesis of AQX-1125
… products has also been investigated. O – Diphenylmethyl and para-methoxybenzyl trichloroacetimidates in refluxing solvent has shown to effectively convert a variety of alcohols to their corresponding ether without disturbing pre-existing functionality. This methodology provides the …

Computational Studies of Protonated Cyclic Ethers and Benzylic Organolithium Compounds
… separation (IPS) of THF-solvated fluorenyl, diphenylmethyl, and trityl lithium was studied computationally. Minimum-energy equilibrium geometries of explicit mono, bis and tris-solvated contact ion pairs (CIPs) and tetrakis-sovlated solvent separated ion pair (SSIPs) were modeled at …

The inclusion behaviour of "wheel-and-axle" host compounds
… (WEB11 ), 4,4'-bis(diphenylmethyl)biphenyl (WEB10). The WEB 11 host compound was found not to include guest molecules. The crystal structures of the non-porous α-phases of these three host compounds and the inclusion compounds were elucidated using single crystal …

CONVENIENT ETHERIFICATION USING TRICHLOROACETIMIDATES AND SYNTHESIS OF AMINOSTEROID SHIP INHIBITORS
… stabilized cations (i.e. the 4-methoxybenzyl and diphenylmethyl group). The use of this new procedure with a number of acid and base sensitive substrates, which are protected in excellent yield without disturbing the delicate functionality present in these molecules, is presented. </p> <p>Cancer …

Trichloroacetimidates as Alkylating Reagents and Their Application in the Synthesis of Pyrroloindoline Natural Products and Synthesis of Small Molecule Inhibitors of Src Homology 2 Domain- Containing Inositol Phosphatase (SHIP)
… reactivity of trichloroacetimidates found that diphenylmethyl trichloroacetimidate, which is a precursor to a highly stabilized carbocation, undergoes facile displacement with carboxylic acids providing the ester product without the need of any exogenous catalyst. Both hindered and unhindered …
