Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, EarlyView.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

Chromium picolinate, zinc picolinate and zinc picolinate dihydrate added for nutritional purposes in food supplements [PDF]

EFSA Journal, 2009
The Panel also noted that, although the safety of zinc itself, in terms of amounts that may be consumed, is outside the remit of this Panel, at the 97.5th percentile the dietary zinc intake from total food only is already close to the UL, as established by the SCF.

Tackling the Reactivity of Propadiene: Palladium Metallaphotoredox Dual Catalyzed Multi‐Component Allylation and Dienylation of Styrenes

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
We presented herein that propadiene can chemodivergently form either an allylic moiety or a dienylic moiety under Pd catalysis. Embedding this reactivity pattern into photocatalysis with DHP as the initial radical source and styrene derivatives as the initial acceptor leads to multi‐component allylation and dienylation.
