AbstractSilylmetalation of alkenes is challenging due to the low reactivity of the substrates. In contrast, carbometalation of alkenes has been realized through several innovative methods, including activation of the reagent and the substrate. A similar approach could be applicable to silylmetalation of alkenes, and we have recently developed a bimetal

Alkene Dialkylation via Triple Radical Sorting
NatureThe development of bimolecular homolytic substitution (SH2) catalysis has expanded cross-coupling chemistries by enabling the selective combination of any primary radical with any secondary or tertiary radical through a radical sorting mechanism1–8 ...

SnO2 Nanosheets for Selective Alkene Gas Sensing
ACS Applied Nano Materials, 2019SnO2 nanosheets with the (101) crystal face mainly exposed were prepared to investigate their sensing properties. The SnO2 nanosheets were ∼150 nm in size and well-dispersed on the sensor chip.

Visualising molecules in 3D is hard. Fortunately, chemists use quite a few of the important stereochemical concepts and terms to describe the shapes of more 2D molecules, like alkenes. So, even if you really came to this book to learn about chirality and conformations in molecules with sp3 carbon atoms, we suggest you venture first into the sp2 world ...

The α-C–H functionalization of piperidine catalyzed by tantalum complex 1 to produce amine 2 was developed (Org. Lett. 2013, 15, 2182) by Laurel L. Schafer at the University of British Columbia. An asymmetric diamination of diene 3 with diaziridine reagent 4 under palladium catalysis to furnish cyclic sulfamide 5 was developed (Org. Lett.
