烯丙醇通过羟基的1，3转座的异构化（方案1a）由某些高氧化态过渡金属0x 0络合物催化，并且已经在工业上通过使用[VO（OR）1]或yWO（OR）1]催化剂在高温下（约100 ℃）进行。130-200 ℃）用于生产萜烯醇。最近已经报道了Mo和V催化剂[*. 31个在25 ℃下有活性。然而，我们发现，在MoO，X，络合物（X= C1，OtBu）的情况下，发生了Mo中心被醇缓慢还原，从而
The isomerization of allyl alcohols by the 1, 3 transposition of an hydroxy group (Scheme 1 a) is catalyzed by certain high oxidation state transition metal 0x0 complexes, and has been carried out industrially by using [VO (OR),] or yWO (OR),] catalysts at high temperatures (ca. 130-200 C) for the production of terpenic alcohols.[‘] Recently Mo and V catalysts have been reported [*. 31 that are active at 25 “C. However, we find that in the case of the MoO, X, complexes (X= C1, OtBu), slow reduction of the Mo”’center by the alcohol takes place, 131 thereby
