Experimentally realized mechanochemistry distinct from force-accelerated scission of loaded bonds [PDF]

open access: yes, 2017
Stretching polymer chains accelerates dissociation of a variety of internal covalent bonds, to an extent that correlates well with the force experienced by the scissile bond.

Tandem Reactivity of Metal−Carbon and Carbon−Silicon Bonds in Mononuclear α‐Silyl Organolithium or Organosodium Complexes Towards CO, CO2 and Heteroallenes

open access: yesAngewandte Chemie, EarlyView.
Anionic α‐silyl alkyl is one of the most used organometallic building blocks and funtional groups. Traditionally, the C─Si bond in these complexes is considered as inert. In this work, we report a series of reactions between mononuclear organo‐lithium and ‐sodium complexes with CO, CO2, or heteroallenes.
