We report herein the synthesis of functionalized styrenes via palladium-catalyzed Suzuki–Miyaura cross-coupling reaction between aryl ketone derivatives and potassium vinyltrifluoroborate. The employment of pyridine-oxazoline ligand was the key to the cleavage of unstrained C[sbnd]C bond. A variety of functional groups and biologically important moleculars were well tolerated. The orthogonal Suzuki–Miyaura coupling demonstrated the synthetic practicability.

A palladium-catalyzed benzylic silylation of diarylmethyl carbonates with silylboranes has been developed. The reaction proceeds smoothly even under external base-free conditions, and the corresponding benzylic silanes are formed in good to high yields. The obtained benzyl silane derivatives can work as the benzylic nucleophiles by the action of a suitable fluoride source and react with some carbon electrophiles to deliver the corresponding benzylic C?C cross-coupled products. Additionally, while still preliminary, the allylic silylation of the isoelectronic allylic carbonates is also achieved.

The zinc salt-catalyzed reduction of α-aryl imino esters, diketones and phenylacetylenes with water as hydrogen source and zinc as reductant was successfully conducted. The presented method provides a low-cost, environmentally friendly and practical preparation of α-aryl amino esters, α-hydroxyketones and phenylethylenes. By using D2O as deuterium source, the corresponding products were obtained in high efficiency with excellent deuterium incorporation rate, which gives a cheap and safe tool for access to valuable deuterium-labelled compounds.
