**Silaborative C-C Coupling Reaction
Silylboranes, 1,3-dienes, and aldehydes are coupled in the presence of a platinum catalyst [Ref. 1]. The reaction provided '''O'''-silylated homoallylic alcohols with high stereoselectivities for the '''syn'''-stereoisomers. The three-component coupling may involve σ-allylplatinum species as a key reactive interemediate.

**Catalytic Hydroalkynylation
The C-H bonds of terminal alkynes are known to add not only to alkynes (homo- and cross-dimerization), but also to highly reactive C=C bonds in allenes, cyclopropenes, and norbornadiene. However, no reaction systems have been established for hydroalkynylation of less reactive C=C bonds. We found that the alkyne C–H bond adds to a carbon-carbon double bond of 1,3-dienes, styrenes, and norbornene at room temperature in the presence of a nickel catalyst in regio- and stereoselective manners [Ref. 2].
