Aryl and vinyl cyclopropanes through the in situ generation of B- cyclopropyl-9-BBN and its Suzuki-Miyaura coupling
Soderquist, John A.,Huertas, Ramon,Leon-Colon, Gisela
, p. 4251 - 4255 (2000)
Dihydroboration of propargyl bromide with 9-BBN-H followed by treatment of the adduct with aqueous sodium hydroxide affords the hydroxy(cycloropropyl)borate complex (1), which undergoes efficient palladium-catalyzed cross-coupling to produce a variety of aryl and vinyl cyclopropanes (2) in good to excellent yields.

1,3-Oxyalkynylation of Aryl Cyclopropanes with Ethylnylbenziodoxolones Using Photoredox Catalysis
Studer, Armido,Zuo, Zhijun

Alkynes and cyclopropanes are vital motifs in chemistry. Herein, a photoredox catalyzed 1,3-oxyalkynylation of aryl cyclopropanes with ethylnylbenziodoxolones (EBXs) in an atom-economic fashion is described. This cascade comprises single-electron oxidatio
Reductive Cyclopropanations Catalyzed by Dinuclear Nickel Complexes
Zhou, You-Yun,Uyeda, Christopher
supporting information, p. 3171 - 3175 (2016/03/12)
Dinuclear Ni complexes supported by naphthyridine-diimine (NDI) ligands catalyze the reductive cyclopropanation of alkenes with CH2Cl2 as the methylene source. The use of mild terminal reductants (Zn or Et2Zn) confers significant functional-group tolerance, and the catalyst accommodates structurally and electronically diverse alkenes. Mononickel catalysts bearing related N chelates afford comparatively low cyclopropane yields (≤20 %). These results constitute an entry into catalytic carbene transformations from oxidized methylene precursors.
Cross-coupling of mesylated phenol derivatives with potassium cyclopropyltrifluoroborate
Molander, Gary A.,Beaumard, Floriane,Niethamer, Terren K.
experimental part, p. 8126 - 8130 (2011/11/12)
C-O activation of mesylates by a palladium catalyst and subsequent cross-coupling with potassium cyclopropyltrifluoroborate have been achieved with high yield. Both electron-enriched and electron-deficient aryl mesylates are suitable electrophilic partners for the Suzuki-Miyaura reaction. The scope was successfully extended to heteroaryl mesylates with yields up to 94%. (Figure presented)
