摘要：

Zirconium (IV) oxide coated on the surface of silica gel was used to absorb Cr(VI) from acidic solutions. This material. in conjunction with t-butyl hydroperoxide, proved to be very useful for allylic oxidations. promoting very clean reactions, with high regioselectivity. (C) 1999 Elsevier Science Ltd.
