Site-selective catalytic deaminative alkylation of unactivated olefins.
Journal of the American Chemical Society, 2019 A catalytic deaminative alkylation of unactivated olefins is described. The protocol is characterized by its mild conditions, wide scope - including the use of ethylene as substrate -, and exquisite site-selectivity pattern for both a-olefins and ...

RNAlater facilitates remote sampling of aquaculture Atlantic salmon liver for proteomic analysis
Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 578-586, December 2022., 2022 Graphical Abstract Proteomes of similar sizes were obtained in samples preserved by snap‐freezing or RNAlater. Proteins involved in transcriptional and translational machinery were affected in RNAlater stored samples. Abundance of published markers for heat and oxidative stress was not affected by snap‐freezing or RNAlater.

Oxidative alkylation of (η5-C5Me5)2TiR (R = Cl, Me, Et, CH=CH2, Ph, OMe, N=C(H)tBu) to (η5-C5Me5)2Ti(Me)R by group 12 organometallic compounds MMe2 [PDF]
, 1991 Oxidative alkylation of Cp*2TiX (Cp*: η5-C5Me5; X = OMe, Cl, N=C(H)tBu) and Cp* 2TiMe by CdMe2 or ZnMe2 gives diamagnetic Cp*2Ti(Me)X and Cp*2TiMe2 respectively, and cadmium or zinc.

N-Heterocyclic Carbene-Catalyzed Decarboxylative Alkylation of Aldehydes.
Journal of the American Chemical Society, 2019 We found that N-heterocyclic carbene catalysis promoted the unprecedented decarboxylative coupling of aryl aldehydes and tertiary or secondary alkyl carboxylic acid-derived redox-active esters to produce aryl alkyl ketones.
