Isomerization of Oxygen-substituted Cyclopropanes by Metal Catalysis

抄録

Highly regio- and stereospecific isomerization reactions of siloxy- and alkoxycyclopropanes were effected under mild reaction conditions by a variety of metal-catalyzed systems using such as Zn (II), Pt (II), Rh (I), and Ni (0). It is noteworthy that the conversion of siloxycyclopropanes to allyl silyl ethers was established by the use of either zinc iodide or Zeise's dimer. The scope, limitations, and mechanisms of isomerization of siloxy- and alkoxy-substituted cyclopropanes are discussed.
