cross-coupling has been achieved through NiH-catalyzed chainwalking and subsequent cross-coupling from two abundant starting materials, alkyl bromides, and carboxylicacids. This strategy allows the direct acylation of the benzylic sp3 C–H bond with high yield as a single regioisomer. As an alternative, the alkyl bromide could be replaced by the proposed olefin intermediate and commercially available n-PrBr

There are described derivatives of gamma-hydroxybutyric acid (GHB), their preparation and their use as GHB pro drugs in the treatment of ethanol addiction. In particular, the derivatives of gamma-hydroxybutyric acid (GHB) have formula (I).
is challenging, especially in asymmetric transformations. With each step in the catalytic cycle promoted by its privileged ligand and different steps well-connected by dynamic ligand exchange, synergistic combination of multiple ligands could potentially enhance the catalytic efficiency and selectivity. Now, this concept has been applied to the NiH-catalyzed asymmetric remote hydroacylation of olefins
