Complexity-generating hydration reactions via gold-catalyzed addition of boronic acids to alkynes [PDF]
, 2012 Boronic acids can serve as organic soluble substitutes for water molecules in the metal-catalyzed hydration of alkynes. The Au-catalyzed addition of boronic acids to alkynes provides an alternative method for enolate generation, which proceeds under ...

Robust NHC-palladacycles-catalyzed Suzuki−Miyaura cross-coupling of amides via C-N activation
Green Synthesis and Catalysis, 2020 Robust NHC-palladacycles (NHC = N-heterocyclic carbene) were synthesized and exhibited high catalytic activity towards Suzuki−Miyaura cross-coupling reactions between inactive amides with N-acetyl/benzyl substituents and aryl boronic acids, producing ...

DSSC Anchoring Groups: A Surface Dependent Decision [PDF]
, 2014 Electrodes in dye sensitised solar cells (DSSCs) are typically nanocrystalline anatase TiO2 with a majority (101) surface exposed. Generally the sensitising dye employs a carboxylic anchoring moiety through which it adheres to the TiO2 surface.

Anomeric sugar boronic acid analogues as potential agents for boron neutron capture therapy
Beilstein Journal of Organic Chemistry, 2019 After the development of accelerators as neutron source, the access to new suitable agents for boron neutron capture therapy (BNCT) became a major need. Among many others, sugar boronic acids have recently attracted attention as boron carriers. Herein we
