In situ generation of Mes2Mg as a non-nucleophilic carbon-centred base reagent for the efficient one-pot conversion of ketones to silyl enol ethers [PDF]
, 2008 Treatment of commercially available MesMgBr with 1,4-dioxane produces the key Mes2Mg reagent in situ which then mediates the deprotonation of ketones to deliver trimethylsilyl enol ethers, at readily accessible temperatures and without any nucleophilic ...

Synthesis of Dithienylcycloalkene Molecular Switches Enabled by a Bench‐Stable Ti‐Complex
Chemistry – A European Journal, EarlyView.Herein we report a set of cycloalkene‐bridged DTEs with ring sizes ranging from 4‐ to 7‐membered rings. The synthesis of these analogs was performed via a key McMurry coupling step, which was enabled by a practical, bench‐stable Ti(IV)‐complex. Remarkably, it is shown that the strained cyclobutene bridge outperforms other rings, even the most commonly ...

European Journal of Organic Chemistry, EarlyView.A method for synthesizing sulfur‐substituted cyclohexenes is reportedthat leverages the η2‐coordination of a phenyl sulfone to [WTp(NO)(PMe3)] (Tp = trispyrazolylborate). Three sequential protonation and nucleophilic additions to the bound arene, followed by oxidative decomplexation, affords functionalized cyclohexenes bearing sp3‐ and sulfur‐enriched ...
