Unusual temperature effects in propene polymerization using stereorigid zirconocene catalysts.

ChemPhysChem 6(9) , 1929-33, (2005)

Free Car-Parrinello molecular dynamics (CPMD) simulations of four diastereomers of the zirconium-propene complexes [{iPr(3-iPr-CpFlu)}ZriBu(C3H6)]+ (Cp=cyclopentadienyl; Flu=fluorenyl) provide valuable insight into the mechanism and stereocontrol of propene p...

Enantioselective route from carbohydrates to cyclooctane polyols.

Org. Lett. 7(3) , 511-3, (2005)

[reaction: see text] A synthetic route to select cyclooctane-1,2,3-triols and 1,2,3,4,5-pentaols has been defined. The starting materials are d-glucose or d-arabinose, and the key steps consist of a zirconocene-promoted ring contraction, a [3,3] sigmatropic r...

Functionalised cyclopentadienyl zirconium compounds as potential anticancer drugs.

Dalton Trans. (39) , 5293-5, (2008)

New neutral and ionic functionalised zirconocene dichloride compounds have been isolated and characterised. The ionic zirconocene exhibits excellent cytotoxicity against a range of human tumour cell lines, which represents the first active anticancer zirconoc...

Formal total synthesis of (+/-)-estrone and zirconocene-promoted cyclization of 2-fluoro-1,7-octadienes and ru-catalyzed ring closing metathesis.

J. Org. Chem. 73(16) , 6202-6, (2008)

A new and diastereoselective method for the synthesis of the estrone skeleton from a substituted styrene based on sequential 3-fold use of Cp 2ZrBu 2 (oxidative addition-alkylation and two cyclization-alkylation sequences) and a ruthenium complex catalyzed RC...

In pursuit of pestalotiopsin a via zirconocene-mediated ring contraction.

Org. Lett. 8(11) , 2429-31, (2006)

[reaction: see text] An asymmetric route from the epimeric beta-hydroxy esters 4 and 5 to the densely functionalized (+)-10 and (-)-10, respectively, is described. Either cyclobutanol can be made available as the predominant product. The levorotatory antipode...

A selective synthesis of hydroxyborate anions as novel anchors for zirconocene catalysts.

Dalton Trans. (21) , 2866-70, (2008)

A new family of hydroxytris(pentafluorophenyl)borate anions [B(C6F5)3OH](-) associated with organic and aprotic cations c+ (imidazolium, pyrrolidinium and phosphonium) has been prepared by a general one-pot synthesis that implies the chloride borate analogues...

Double carbonylation of zirconocene-alkyne complexes.

Chem. Commun. (Camb.) (19) , 2495-6, (2005)

Zirconocene-alkyne complexes prepared from Cp2ZrBu2, phosphines and alkynes reacted with CO to give double carbonylation products, 4-hydroxycyclobuten-1-one derivatives after hydrolysis.

Zirconocene-mediated synthesis of cyclobutabenzenes.

Org. Lett. 10(20) , 4469-71, (2008)

A new, mild, one-pot method for the synthesis of cyclobutabenzenes by the zirconium-promoted cross-coupling reaction of aryllithium compounds and alkenyl bromides is reported. Formation of an arynezirconocene complex and its regioselective coupling with an al...

Medium-sized carbocycles by a zirconocene-catalyzed tandem formal ring expansion-magnesation reaction of alkenyl-substituted cyclic enol ethers.

Org. Lett. 9(16) , 3081-4, (2007)

A new regio- and stereoselective zirconocene-catalyzed reaction for the synthesis of medium-sized rings is described. The global reaction supposes a formal ring expansion of a cyclic enol ether to give a functionalized carbocycle.

Tandem insertion of halocarbenoids and lithium acetylides into zirconacycles: a novel rearrangement to zirconium alkenylidenates by β-addition to an alkynyl zirconocene.

Chemistry 17(17) , 4896-904, (2011)

Tandem insertion of 1,1-dihalo-1-lithio species (halocarbenoids) and lithium alkynides into zirconacyclopentenes and zirconcyclopentanes affords carbocyclic products in high yields via an unusual rearrangement that probably involves addition of an organolithi...
