Boron Arylations of Subporphyrins with Aryl Zinc Reagents [PDF]
Chemistry – A European Journal, 2016 AbstractBoron arylations of B‐(methoxo)triphenylsubporphyrin have been developed with a combined use of ArZnI⋅LiCl and trimethylsilyl chloride. Aryl zinc reagents bearing bromo, cyano, amide, and ester groups can be employed for the B‐arylation reaction to provide the corresponding B‐arylated subporphyrins in moderate yields.

Surface enhanced infrared absorption spectroscopy for graphene functionalization on copper [PDF]
Carbon, 124, 250-255 (2017), 2021 The monolayer form of CVD graphene is imposing crucial challenges in characterization of the targeted covalent functionalization due to the low amount of grafting moieties on the surface, which in turn hampers drawing conclusions about reactivity-properties relationships. Due to the growing interest in chemically modified graphene new, reliable and non-

Palladium-catalyzed acetylation of arenes. [PDF]
, 2014 A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in ...

Indacenodithiophene homopolymers via direct arylation: direct polycondensation versus polymer analogous reaction pathways [PDF]
Macromolecules 52 (2019) 7251-7259, 2019 Indacenodithiophene (IDT) based materials are emerging high performance conjugated polymers for use in efficient organic photovoltaics and transistors. However, their preparation generally suffers from long reaction sequences and is often accomplished using disadvantageous Stille couplings.

Computational Insights into Electronic Excitations, Spin-Orbit Coupling Effects, and Spin Decoherence in Cr(IV)-based Molecular Qubits [PDF]
, 2022 The great success of point defects and dopants in semiconductors for quantum information processing has invigorated a search for molecules with analogous properties. Flexibility and tunability of desired properties in a large chemical space have great advantages over solid-state systems. The properties analogous to point defects were demonstrated in Cr(

Microwave-mediated synthesis of N-methyliminodiacetic acid (MIDA) boronates [PDF]
, 2014 A library of over 20, mainly aryl or heteroaryl, N-methyliminodiacetic acid (MIDA) boronates have been synthesised. A rapid microwave-mediated (MW) method (5–10 min) has been developed using polyethylene glycol 300 (PEG 300) as solvent.
