Abstract

Isomerization of primary allylic alcohols proceeds in dichloromethane at 25° C in the presence of the catalyst prepared in situ from VO (acac) 2 or MoO 2 (acac) 2, and Me 3 SiOOSiMe 3 to give tertiary isomers in good yields. The catalysts are also effective for the rearrangements of sec.→ tert. allylic alcohols. The isomerization of an allenyl allylic alcohol, 6-methyl-1, 2, 5-heptatrien-4-ol, gives either (E)-2-methyl-3, 5, 6-heptatrien-2-ol or (E)-6- ...
