TL;DR: Les complexes du titre reagissent photochimiquement avec les olefines pour donner de nouveaux complexes alcene-carbene dans lesquels les 2 fonctions sont en trans as mentioned in this paper.
37 citations
TL;DR: In this article, the reaction of allylamine with (CO)5WC(OCH2CH3)CH3 gives two isomeric aminocarbene complexes 2E and 2Z, which were fully characterized by X-ray diffraction.
26 citations
TL;DR: In this article, the synthesis of aminocarbene complexes of tungsten, containing either a free or a coordinated double bond, was described, in which the unsaturated alkyl chain is coordinated to the metal.
25 citations
TL;DR: Carbene complexes of tungsten, bearing a co-ordinated double bond two carbons away from the carbene function, react with alkynes to give, after insertion of the alkyne, bicyclo[4.1.0]heptane derivatives as a result of cyclopropanation of the double bond by the newly formed carbene complex as mentioned in this paper.
Abstract: Carbene complexes of tungsten, bearing a co-ordinated double bond two carbons away from the carbene function, react with alkynes to give, after insertion of the alkyne, bicyclo[4.1.0]heptane derivatives as a result of cyclopropanation of the double bond by the newly formed carbene complex.
24 citations
TL;DR: In this paper, the first heteroatom-substitued μ-alkylidene complexes of tungsten were synthesized, starting from conjugated Fischer-typ carbene complexes (CO) 5 WC(OR)CH-CHR, and an X-ray diffraction study has revealed the presence of five CO groups on each metal center.
23 citations
TL;DR: In this paper, a general synthesis of alkene-carbene complexes of tungsten, chromium and rhenium, containing a six-membered ring system, is outlined and the crystal structure of two new complexes of this type, (CO) 4 WC(OEt)
21 citations
TL;DR: In this article, the X-ray structure of Lanthanum tris(tetraphenylimidodiphosphinate)3 was established, which can be used successfully as n.m.r. shift reagents in association with acids and phenols.
Abstract: Lanthanum tris(tetraphenylimidodiphosphinate){La(tpip)3} reacts with ethyl acetate to give a stable 1 : 1 adduct, the X-ray structure of which has been established; complexes of the general structure Ln(tpip)3 can be used successfully as n.m.r. shift reagents in association with acids and phenols.
16 citations
TL;DR: Chromium complexes containing the bidentate aminocarbene-alkene ligand react with alkynes to give, after insertion followed by an intramolecular cyclopropanation reaction, azabicyclo[410]heptene systems.
10 citations
TL;DR: In this paper, the μ-alkylidene complex Fe2[μ-CH2(CO)8] reacts with CO and ROH to give mainly the ester CH3CO2R.

TL;DR: In this paper, the μ-alkylidene complex Fe2[μ-CH2(CO)8] reacts with CO and ROH to give mainly the ester CH3CO2R.
Abstract: Whereas μ-alkylidene complex Fe2[μ-CH2(CO)8] reacts with CO and ROH to give mainly the ester CH3CO2R, the μ-alkylidene complex Pd2[μ-CH2(PPh2CH2PPh2]I2 gives the malonate CH2(CO2R)2 with a selectivity of 88%.
