Mo-Au Combo Catalysis for Rapid 1,3-Rearrangement of Propargyl Alcohols into a,b-Unsaturated Carbonyl Compounds.

[摘要]：The combination of Mo and cationic Au catalysts dramatically accelerated the rearrangement of diverse propargyl alcs., which includes a short reaction time, mild conditions, and high product yields. A practical application to the highly challenging primary propargyl alcs. and the N-alkynyl amides was achieved. Thus, rearrangement of HOCH2CYCCH2CH2Ph in toluene contg. bis(acetylacetonato)dioxomolybdenum, AuCl(PPh3), and silver triflate gave 93% H2C:CHCOCH2CH2Ph.
