Ruthenium catalyzed enyne cycloisomerizations and hydroxycyclizations with skeletal rearrangement
Faller,Fontaine, Philip P.
, p. 1912 - 1918 (2006)
A neutral arene-tethered ruthenium complex was found to be a catalyst precursor for enyne cycloisomerizations and hydroxycyclizations. The observed products were the result of a skeletal rearrangement process, and include an unusual cyclization to form a six-membered ring. Labeling studies on the six-membered ring product are in accord with an electrophilic activation mechanism that proceeds via cationic cyclopropyl carbene intermediates.
Complementary Reactivity of 1,6-Enynes with All-Metal Aromatic Trinuclear Complexes and Carboxylic Acids

The distinct reactivity of 1,6-enynes in the presence of a trinuclear metal complex activated by a carboxylic acid is presented. The triplatinum catalyst enables the cyclization of the substrate and subsequent incorporation of a nucleophile in the final product. In contrast, sequential cyclization/double bond shift occurs under analogous conditions in the presence of the corresponding tripalladium complex.
Diastereoselective cycloisomerizations of enediynes via palladium catalysis
Trost,Shi
, p. 12491 - 12509 (2007/10/02)
Considerations of atom economy drive a search for reactions that are simple additions which, performed intramolecularly, are cycloisomerizations. Exposure of acyclic enediynes to a catalyst generated by mixing a Pd(0) complex with acetic acid normally in
Ligand dependence of molybdenum-catalyzed alkylations. Molybdenum-isonitrile complexes as a new class of highly reactive alkylation catalysts
Trost, Barry M.,Merlic, Craig A.
, p. 9590 - 9600 (2007/10/02)
A series of molybdenum complexes bearing α-diimine, N,N′-diarylideneethylenediamine, and isonitrile ligands have been prepared and evaluated for their ability to catalyze alkylations by using allyl acetates and especially allyl sulfones. (bpy)Mo(CH3
