Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

open access: yesAngewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...

Asymmetric Organocatalytic Synthesis of Sulfone‐Containing (Dihydro)pyrans via Formal (4+2)‐Cycloadditions of Allenylsulfones or Propargylsulfones and Michael Acceptors

open access: yesChemCatChem, Accepted Article.
The activation of electron poor allenes with Lewis base catalysts allows for unique transformations and chiral isochalcogenoureas were recently introduced as powerful catalysts for allenoate‐based (4+2)‐cycloadditions. We herein now report the use of these catalysts for the activation and control of allenylsulfones and propargylsulfones for asymmetric (

Polymeric Carbon Nitride‐Photocatalyzed Aerobic Epoxidation of Alkenes: Application to a Sustainable Synthesis of Rose Oxide

open access: yesChemSusChem, Accepted Article.
A urea‐based pristine polymeric carbon nitride catalyzes the aerobic epoxidation of citronellol under visible light irradiation with low‐power blue LEDs. Formation of 6,7‐epoxycitronellol in this reaction is remarkably selective yet relatively slow requiring 72 h of continuous irradiation.

Phosphanyl‐Substituted Tetrylenes and Ditetrelenes – Impact of Steric Bulk on Tetrylene/Ditetrelene Stability

open access: yesEuropean Journal of Inorganic Chemistry, Accepted Article.
Phosphorus‐substituted tetrylenes and ditetrelenes remain something of a rarity. The reaction between SnCl2 and two equivalents of (Dep2P)Li at low temperature gave the bis(phosphanyl)stannylene {(Dep)2P}2Sn (4Sn), although this compound decomposes in solution at room temperature (Dep = 2,6‐Et2C6H3).
