A Carbene‐Stabilized Boryl‐Phosphinidene
Chemistry – A European Journal, 2022 AbstractHerein, the synthesis and characterization of the carbene‐stabilized boryl phosphinidenes 1–3 are reported. Compounds 1–3 are obtained by reacting Me‐cAAC=PK (Me2‐cAAC=dimethyl cyclic(alkyl)(amino)carbene) and dihaloaryl borane in toluene. All three compounds were characterized by X‐ray crystallography. Quantum mechanical studies indicated that

Palladium-catalyzed borylation of aryl (pseudo)halides and its applications in biaryl synthesis
Chemistry Central Journal, 2018 A facile and efficient palladium-catalyzed borylation of aryl (pseudo)halides at room temperature has been developed. Arylboronic esters were expeditiously assembled in good yields and with a broad substrate scope and good functional group compatibility.

Photocatalytically Active Mechanically Interlocked Carbon Nanotubes. [PDF]
SmallMechanically interlocked CNTs (MINTs) are studied as heterogeneous photocatalysts. Two different motifs are presented, which own enhanced activity versus homogeneous systems at very low loadings, high TON, excellent recyclability, varied scope and no leaching.
