This is a review of papers published in the year 2009 that focus on the synthesis, reactivity,
or properties of compounds containing a carbon-transition metal double or triple bond.

An rapid and mild synthetic route for the preparation of cyclic tetrasubstituted platforms via
ruthenium-catalyzed ring-closing metathesis (RCM) has been developed. This process …

The enol ether-olefin ring-closing metathesis reaction has been employed to generate 2, 3-
dihydrofurans that are equipped with a leaving group. These substrates are at the correct …

A range of palladacyclic, platinacyclic, and pincer-based catalysts have been tested for
activity in 1, 4-conjugate addition reactions. π-Acidic palladacycles show excellent activity at …

The use of vinyl-or alkynyl derivatives of the type CC–X or CC–X (where X is an heteroatom)
as substrates for metathesis increases further this reaction's versatility. Selected examples …

An efficient protocol for the synthesis of thiazoline derivatives via electrophilic cyclization of
N‐allyl thiourea derivatives with the low‐cost and readily available cupric halides has been …

The ring-closing metathesis (RCM) of dienes that contain at least one participating
heteroatom-substituted olefin is reviewed (olefins substituted with O, N, S, P, Si, B, and …

An entry to new classes of nitrogen-containing heterocycles featuring both a cyanamide and
an unsaturated 5-, 6-or 7-membered ring is reported. They can be readily obtained by ring …
