Gold(I)-polyoxometalate hybrid complexes 1-4 ([PPh3AuMeCN] xH4-xSiW12O40, x=1-4) were synthesized and characterized. The structure of the primary gold(I)- polyoxometalate 1 (x=1) was fully ascertained by XRD, FTIR, 31P and 29Si magic-angle spinning (MAS) NMR, mass spectroscopy, and SEM-energy dispersive X-ray spectroscopy (EDX) techniques. Moreover, this complex exhibited better catalytic activity and selectivity compared with standard, homogeneous, gold catalysts in the new rearrangement of propargylic gem-diesters. Gold(I)-polyoxometalate hybrid complexes ([AuPPh 3MeCN]xH4-xSiW12O40, x=1-4) were synthesized and characterized. [AuPPh3MeCN]H 3SiW12O40 exhibited better catalytic activity and selectivity compared with standard, homogeneous, gold catalysts in the new rearrangement of propargylic gem-diesters (see scheme).

Reaction of trimethylsilylenol ethers and Vilsmeier's reagent leads to the corresponding regiocontrolled β-dicarbonyl compounds with high to good yields.
STEREOSELECTIVE SYNTHESIS AND THERMAL BEHAVIOR OF (Z)-EPOXYHEXENYNES: A SIMPLE AND GENERAL ROUTE TO 2-VINYLFURANS
Eberbach, Wolfgang,Roser, Joachim
, p. 2797 - 2802 (2007/10/02)
An efficient approach for the synthesis of 2,3-disubstituted furans (2a-j/3a-j) is described by using the thermally induced rearrangement of epoxyhexenynes (1a-j) which are prepared by streoselective synthesis of the (Z)-pentenynals 10 and subsequent Darz
