Chemical Science (IF: 9.556)



1. Catalyst shuttling enabled by thermoresponsive polymeric ligand: facilitating efficient cross-couplings with continuously recyclable ppm levels of palladium

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC02171J



Researchers from Fudan University have designed a biphasic catalyst migration mode that enables efficient cross-coupling as well as rapid and complete on-site recycling of catalysts. The new thermoresponsive catalyst composed of Pd and polymeric phosphine ligand was used in Suzuki-Miyaura cross-coupling and enables an ultra-low Pd loading method with catalysts transferring between aqueous and organic phases. The system works on 73 examples in up to 99% isolated yields.

2. Redox-neutral ortho-C–H amination of pinacol arylborates via palladium(II)/norbornene catalysis for aniline synthesis

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC02759A

Scientists at Wuhan University report a new phosphine free method for the synthesis of structurally diverse anilines, which is scalable and tolerates a wide range of functional groups. This method is very useful for synthesing halogenated anilines, which can be difficult to do by other synthetic strategies. Deuterium labelling studies show that the reaction goes through a redox-neutral ipso-protonation mechanism. This study should be a valuable strategy for others wishing to synthesise anilines.

Organic Chemistry Frontiers (IF: 5.076)



1. Ligandless nickel-catalyzed transfer hydrogenation of alkenes and alkynes using water as the hydrogen donor

Org. Chem. Front., 2019, 6, 2619-2623

DOI: 10.1039/C9QO00616H


The first general route for nickel-catalyzed transfer hydrogenation reaction of alkenes and alkynes using water as the hydrogen source has been developed. The method features the use of inexpensive and air-stable nickel(II) salt as the pre-catalyst and zinc powder as a reducing agent, allowing the TH reaction to occur under mild reaction conditions with a wide substrate scope and functional group tolerance. No ligand was required for this reaction. The reaction has also been applied successfully to the reduction of nitrogen-containing heterocycles.

2. A novel chiral DMAP–thiourea bifunctional catalyst catalyzed enantioselective Steglich and Black rearrangement reactions

Org. Chem. Front., 2019, Advance Article

DOI: 10.1039/C9QO00691E



The first novel and efficient chiral DMAP–thiourea bifunctional catalyst has been successfully developed and applied in highly enantioselective acyl-transfer reactions. A series of 1,3-oxazolyl carbonates are efficiently transformed to C-carboxyazlactones (Steglich rearrangement) by employing 5 mol% of this bifunctional nucleophilic catalyst with good yields and excellent enantioselectivities (up to 90% yield and 97% ee), and 2-benzofuranylcarbonates are also converted to 3,3-disubstituted benzofuran-2-ones (Black rearrangement) with satisfactory asymmetric induction (up to 92% yield and 87% ee).
