Journal ArticleDOI
A Rational Approach towards the Nucleophilic Substitutions of Alcohols “on Water”
Pier Giorgio Cozzi,Luca Zoli +1 more
TL;DR: The direct substitution of alcohols “on water” without added Brønsted or Lewis acid is possible; the reaction is related to the stability of the corresponding carbocation, and the lifetimes of carbocations can be increased substantially by the introduction of electron-donating substituents on the aryl ring.
Journal ArticleDOI
Decarboxylative Trifluoromethylation of Aliphatic Carboxylic Acids
TL;DR: An efficient method for the conversion of carboxylic acids to trifluoromethyl groups via the combination of photoredox and copper catalysis is disclosed, which tolerates a wide range of functionality including heterocycles, olefins, alcohols, and strained ring systems.
Journal ArticleDOI
Dual Organocatalysis: Asymmetric Allylic–Allylic Alkylation of α,α‐Dicyanoalkenes and Morita–Baylis–Hillman Carbonates
TL;DR: The first highly enantioselective allylic-allylic alkylation of alpha,alpha-dicyanoalkenes and Morita-Baylis-Hillman carbonates by dual catalysis of (DHQD)(2)AQN and (S)-BINOL has been investigated.
Journal ArticleDOI
Scope of the asymmetric intramolecular stetter reaction catalyzed by chiral nucleophilic triazolinylidene carbenes.
TL;DR: A highly enantioselective intramolecular Stetter reaction of aromatic and aliphatic aldehydes tethered to different Michael acceptors has been developed and the substrate scope has been examined and found to be broad.

A single component ratiometric pH probe with long wavelength excitation of europium emission
Robert Pal,David Parker +1 more
TL;DR: Following excitation in therange 370-405 nm, the emission spectrum of a cell permeable macrocyclic Eu(III) complex incorporating an N-methylsulfonamide moiety changes form with pH, allowing ratiometric pH measurements in the range 6 to 8.
