Due to their intrinsic high reactivity, isolation of tin(0) complexes remains challenging. Herein, we report the synthesis of a silylene-stabilized ditin(0) complex (2) by reduction of a silylene-supported dibromostannylene (1) with 1 equivalent of ...

Facile and general electrochemical deuteration of unactivated alkyl halides
Deuterium-labelled compounds are useful for mechanistic studies and pharmaceutical science, but syntheses are not trivial. Here, the authors report deuteration of unactivated alkyl (pseudo)halides driven by electrochemical force, using deuterium oxide as

Organic Matter in Cometary Environments [PDF]
Comets contain primitive material leftover from the formation of the Solar System, making studies of their composition important for understanding the formation of volatile material in the early Solar System. This includes organic molecules, which, for the purpose of this review, we define as compounds with C–H and/or C–C bonds.

Metal-free electrochemical dihydroxylation of unactivated alkenes
Herein, a metal-free electrochemical dihydroxylation of unactivated alkenes is described. The transformation proceeds smoothly under mild conditions with a broad range of unactivated alkenes, providing valuable and versatile dihydroxylated products in ...

Ketone α-alkylation at the more-hindered site
Control of the regioselectivity of α-alkylation of carbonyl compounds is a longstanding topic of research in organic chemistry. By using stoichiometric bulky strong bases and carefully adjusting the reaction conditions, selective alkylation of ...
