Synthesis of β-arylated alkylamides via Pd-catalyzed one-pot installation of a directing group and C(sp3)–H arylation

open access: yesBeilstein Journal of Organic Chemistry, 2016
The synthesis of β-arylated alkylamides via alkyl C–H bond arylation has been realized by means of direct one-pot reactions of acyl chlorides, aryl iodides and 8-aminoquinoline. Depending on the structure of the starting materials, both single and double

N-Benzo[c][1,2,5]thiazol-4-yl-3-trifluoromethylbenzamide

open access: yesMolbank, 2019
The title compound, N-benzo[c][1,2,5]thiazol-4-yl-3-trifluoromethylbenzamide (1) was synthesized by reacting 3-trifluoromethylbenzoyl chloride (4) and 4-aminobenzo[c][1,2,5]thiadiazole (5). The compound was characterized by various spectroscopic methods (

Catalytic Undirected Meta‐Selective C–H Borylation of Metallocenes

open access: yesAdvanced Science, 2023
Metallocenes are privileged backbones in the fields of synthetic chemistry, catalysis, polymer science, etc. Direct C–H functionalization is undoubtedly the simplest approach for tuning the properties of metallocenes.

Preparing the foundations for video-based, practice-placement support: establishing the role from a students’ perspective [PDF]

open access: yes, 2012
Currently, many placement-based health programme students within the UK are supported through face-to-face visits from university staff. Whilst cited in literature as being of value, the face-to-face nature of this contact is not supported.

Palladium-Catalyzed ortho-Arylation of Carbamate-Protected Estrogens [PDF]

open access: yes, 2016
The palladium-catalyzed ortho-arylation of diethylcarbamate-protected estrone and estriol with aryl iodides, gives the 2-arylated analogues. Subsequent removal of the carbamate directing group furnishes 2-arylated estrone, estradiol or estriol depending ...

Maximal subgroups of multi-edge spinal groups [PDF]

open access: yes, 2016
A multi-edge spinal group is a subgroup of the automorphism group of a regular p-adic rooted tree, generated by one rooted automorphism and a finite number of directed automorphisms sharing a common directing path. We prove that torsion multi-edge spinal

Grouping principles in direct competition

open access: yesVision Research, 2013
We (1) introduce a primed flanker task as an objective method to measure perceptual grouping, and (2) use it to directly compare the efficiency of different grouping cues in rapid visuomotor processing. In two experiments, centrally presented primes were succeeded by flanking targets with varying stimulus-onset asynchronies (SOAs).

Palladium-Catalyzed Oxidation of β-C(sp3)-H Bonds of Primary Alkylamines through a Rare Four-Membered Palladacycle Intermediate. [PDF]

open access: yes, 2020
Site-selective functionalizations of C-H bonds are often achieved with a directing group that leads to five- or six-membered metallacyclic intermediates. Analogous reactions that occur through four-membered metallacycles are rare. We report a challenging

Borane as an efficient directing group. Stereoselective 1,2-addition of organometallic reagents to borane P-stereogenic N-phosphanylimines [PDF]

open access: yes, 2017
In non-coordinating solvents, borane was shown to be an efficient directing group for the stereoselective 1,2-addition of organolithium reagents to P-stereogenic N-phosphanylimines. Selectivity was reversed in coordinating solvents. This process can lead

Sensory over-responsivity and social cognition in ASD: Effects of aversive sensory stimuli and attentional modulation on neural responses to social cues. [PDF]

open access: yes, 2018
Sensory over-responsivity (SOR) is a common condition in autism spectrum disorders (ASD) that is associated with greater social impairment. However, the mechanisms through which sensory stimuli may affect social functioning are not well understood.
