A systematic study on the effects of Lewis or Br?nsted acid co-catalysts in gold-catalyzed reactions was undertaken using representative reactions (O-, N-, and C-nucleophilic additions to alkynes). Through these reactions, it was demonstrated that an acidic co-catalyst can increase the catalyst turnover significantly, enabling practical reaction rates at competitive catalyst loadings (1 mol %). Further investigation is currently underway to improve the understanding of the subtle principles underlying these experimental observations.
Synthesis of indenyl ethers by gold(I)-catalyzed intramolecular carboalkoxylation of alkynes
Dube, Pascal,Toste, F. Dean

The gold(I)-catalyzed carboalkoxylation of alkynes to form indanone derivatives from readily available ortho-acetylenic benzylic ethers is described. Importantly, the gold(I)-catalyzed rearrangement of enantioenriched benzylic ethers proceeds with chirali
Generation and Trapping of Cyclopropenes from 2-Alkoxy-1,1-dichlorocyclopropanes
Mueller, Paul,Pautex, Nicole
, p. 55 - 64 (2007/10/02)
In presence of crown ether, 2-alkoxy-1,1-dichlorocyclopropanes react with t-BuOK/THF preferentially via ring opening to 2-chloroalk-2-en-1-ones and alkynones or to chlorocyclopropenes.The latter may be intercepted with 1,3-diphenylisobenzofuran, but in th
Solvent, chelation and concentration effects on the benzannulation reaction of chromium carbene complexes and acetylenes

The reactions of a number of chromium carbene complexes (CO)5Cr=C(OMe)R (R = Ph, o-OMePh, p-OMePh, o-O-tBuPh, 1-C6H9, 1-C5H7O) were examined with a variety of acetylenes (R'CCR2, R1, R2 = H, Me, Et, n-Pr, Ph, SiMe3) in sol
