The commercially available and bottleable complex NiCl2(dppe) serves as a catalyst for the highly Markovnikov-selective hydroboration of styrene derivatives that affords the desired Markovnikov products in high yield.

We have developed a hydrosilylation reaction of alkenes using 1,1,3,3-tetramethyldisiloxane (TMDS) as a surrogate for Me 2 SiH 2 in the presence of NaOMe, catalyzed by a bench-stable nickelpincer complex supported by a monoanionic O,N,P-tridentate ligand. The reaction of styrene derivatives proceeds smoothly under mild reaction conditions to provide the hydrosilylated products in high yields with high Markovnikov selectivity. This protocol shows a wide substrate scope and is compatible with a wide range of functional groups. Secondary hydrosilanes are also suitable under the present reaction conditions and furnish the desired products in high yields.

We have developed a Wacker-Tsuji-Type oxidation reaction of styrene derivatives catalyzed by a bench-stable ferrate. This oxidation reaction, which uses molecular oxygen as the sole oxidant and 1,1,3,3-tetramethyldisiloxane (TMDS) as a reductant, can realize the oxidation of styrene derivatives to ketones in good yield. In addition, this ferrate-based system can achieve the cleavage of the CÀ C double bond of α-phenyl-substituted styrene derivatives, providing the one-carbon-degraded ketones in good yield.
