Allylsilanes in Organic Synthesis − Recent Developments
TL;DR: A survey of the most recent advances in this field is described in this paper, including transformations of allylsilanes through electrophilic, radical and organometallic processes, with particular emphasis on the stereocontrol arising from these processes.

New Developments in the Cyclopentadienyl Chemistry of the Alkaline-Earth Metals
TL;DR: Recent developments in the chemistry of cyclopentadienyl derivatives of the alkaline-earth (group 2) metals are reviewed in this paper, where new complexes and their applications in organometallic and materials synthesis reflect the growing number of ways that can be used to manipulate the alkalinear-earth−cyclopentadiyl bond.

Catalytic Asymmetric [3+2] Annulation of Allylsilanes with Isatins: Synthesis of Spirooxindoles
TL;DR: In the presence of chiral ScCl2(SbF6)·BIOP, prepared in situ, and TmsCl as an essential promoter, the desired spirooxindoles are obtained with excellent enantioselectivities at room temperature as mentioned in this paper.

The interaction of silicon with positively charged carbon
TL;DR: Sommer et al. as mentioned in this paper showed that a silyl group beta to the leaving group enormously enhances the rate of solvolysis, and that a gamma silyal group also has an enhancing effect, but that an alpha sily l group actually decreases reactivity in comparison with hydrocarbon models.
