organic synthesis. One of the priorities in this area is exploration of stable carbene …

Carbonyl ylides have proven to be powerful synthons for the efficient construction of various
valuable O‐heterocycles, and the formation of carbonyl ylides by the reaction of metal …

cis-Delivery of H2 to the π-system of an unsaturated substrate is the canonical course of
metal catalyzed hydrogenation reactions. The semireduction of internal alkynes with the aid …

The hydrogenation of internal alkynes with [Cp* Ru]-based catalysts is distinguished by an
unorthodox stereochemical course in that E-alkenes are formed by trans-delivery of the two …

A wide variety of annulation reactions have been developed using Cp∗ RuCl (cod) and
related complexes as precatalysts. This digest highlights recent progress in Cp∗ RuCl …

Traditional rhodium carbene chemistry relies on the controlled decomposition of diazo
derivatives with [Rh2 (OAc) 4] or related dinuclear Rh (+ 2) complexes, whereas the use of …

An unprecedented palladium-catalyzed novel carbene/alkyne metathesis cascade reaction
of alkyne-tethered enynones is described. This reaction affords fused polyheterocycles in …
