Interrupted Barton–Zard Reaction/Friedel–Crafts Alkylation Telescoped Reaction for the Synthesis of Pyrrolo[3,4‐b]indole Cores

open access: yesAsian Journal of Organic Chemistry, EarlyView.
An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...

Phosphinoisocyanide/Alkyne Cycloaddition: Generation of Azaphospholylidene (NPHC) Ligands

open access: yesAngewandte Chemie, EarlyView.
Rare examples of nitrogen phosphorus heterocyclic carbene (NPHC) complexes of group 6 and 7 metals arise from a facile [3 + 2] cycloaddition of phosphinoisocyanides (LnM‐CNPR2) with activated alkynes. The NPHC ligands are shown to be comparatively π‐acidic and the group 6 examples undergo facile transfer of the intact carbene to gold(I) centres ...

Ein immobilisierter, fester molekularer Rh‐Katalysator für die reduktive Hydroformylierung von 1‐Octen

open access: yesAngewandte Chemie, EarlyView.
Die reduktive Hydroformylierung von Olefinen kann durch Rh katalysiert werden, das auf einem hochverzweigten, Amin‐enthaltenden Polymer immobilisiert wurde. So wird effizientes Rezyklisieren, eine hohe Selektivität und Alkohol‐Ausbeute erreicht.

Lewis Acidity of the SbCl3/o‐chloranil System

open access: yesAngewandte Chemie, EarlyView.
An SbCl5 surrogate from easy‐to‐handle reagents! The putative SbCl3(o‐C6O2Cl4) synthon is calculated to be more Lewis acidic than SbCl5. Even if endergonic, its formation from SbCl3 and o‐chloranil can be driven by Lewis base coordination, leading to the corresponding adducts.
