Homoallyl-cyclopropylcarbinyl cation manifold. Trimethylsilyl versus aryl stabilization

(Chemical Equation Presented) A series of E- and Z-1-aryl-5-trimethylsilyl- 3-buten-1-yl trifluoroacetates were solvolyzed in CD3CO2D, and rates of reaction as well as products derived from these reactions were determined. Hammett pl

Preparation of (Z)-alk-2-ene-1,5-diols by the titanocene(II)-promoted cyclization of thioacetals possessing a terminal carbon-carbon double bond

Titanocene(II)-promoted ring-closing metathesis of the titanium carbene complexes prepared from [2,2-bis(phenylthio)ethyl](but-3-enyloxy)dimethylsilanes or dimethyl(prop-2-enyl)silyl ethers of 3,3-bis(phenythio)propanols gave seven-membered cyclic unsatur

Indenylidene complexes of ruthenium: Optimized synthesis, structure elucidation, and performance as catalysts for Olefin metathesis - Application to the synthesis of the ADE-ring system of nakadomarin A

An optimized and large scale adaptable synthesis of the ruthenium phenylindenylidene complex 3 is described which employs commercially available diphenyl propargyl alcohol 5 as a stable and convenient carbene source. Previous ambiguities as to the actual

Cationic ruthenium allenylidene complexes as catalysts for ring closing olefin metathesis

A series of well accessible cationic ruthenium allenylidene complexes of the general type [(η6-arene)(R3P)RuCl(=C=C=CR′2)] + X- is described which constitute a new class of pre-catalysts for ring closing olefin metathesis reactions (RCM) and provide an unprecedented example for the involvement of metal allenylidenes in catalysis. They effect the cyclization of various functionalized dienes and enynes with good to excellent yields and show a great tolerance towards an array of functional groups. Systematic variations of their basic structural motif have provided insights into the essential parameters responsible for catalytic activity which can be enhanced further by addition of Lewis or Bronsted acids, by irradiation with UV light, or by the adequate choice of the "non-coordinating" counterion X-. The latter turned out to play a particularly important role in determining the rate and selectivity of the reaction. A similarly pronounced influence is exerted by remote substituents on the allenylidene residue which indicates that this ligand (or a ligand derived thereof) may remain attached to the metal throughout the catalytic process. X-ray crystal structures of the catalytically active allenylidene complexes 3b · PF6 and 15 · OTf as well as of the chelate complex 10 required for the preparation of the latter catalyst are reported.

Functionalised cyclic allyl silanes have been prepared by the ring closing metathesis of allyldimethylsilyl ethers of homoallylic alcohols. Treatment of these allyl silanes with aldehydes in the presence of boron trifluoride etherate gives high yields of

Synthesis of oxygenated hererecycles from cyclic allylsiloxanes using ring-closing olefin metathesis
