DOI: 10.1002/cctc.201800454
Abstract: Herein, we introduce a new class of bench‐stable N‐heterocyclic carbene (NHC) nickel‐precatalysts for homogeneous nickel‐catalysis. The nickel(II) complexes are readily activated to Ni0 in situ under mild conditions, via a proposed Heck‐type mechanism. The precatalysts are… read more here.

DOI: 10.1021/acs.orglett.8b00560
Abstract: A new triazine-based oxidizing reagent, 2-hydroperoxy-4,6-diphenyl-1,3,5-triazine (Triazox), has been developed. The reagent can be synthesized from inexpensive starting materials and is a bench-stable solid that is isolable in pure form. Epoxidation of alkenes possessing acid-sensitive… read more here.

Abstract: The commercially available and experimentally convenient (bp 65 °C) difluoromethyltrimethylsilane (TMSCHF2) is proposed as a valuable difluoromethylating transfer reagent for delivering the CHF2 moiety to various heteroatom-based electrophiles. Upon activation with an alkoxide, a conceptually… read more here.

DOI: 10.1055/s-0037-1610087
Abstract: A procedure for the α-arylation of α,α-disubstituted esters and ketones to generate quaternary carbon centers is described. The developed protocol is operationally simple and employs an air- and moisture-stable dinuclear Pd(I) complex [Pd(μ-I)(Pt-Bu3)]2 to mediate… read more here.
